So far we printed one after the last received message, which doesn't
make much sense of course.
Now only print one if there is not already one present.
This is because the actual command that parses itself (cmd_logging) returns false if it didn't get the expected parameters.
Handing the printing however is done by another function. This function is added to the Command struct as setting_function.
So if this is set, and the actual command returns false. We should just call the setting_function and not print the error message.

The last 3 commits added basic support.
Thanks @aaptel!
This commit adds basic settings interface to use it.
See `/color on|off`.
We still have to enable settings for color blindness.
And maybe another setting to decide whether to color the
occupantslist/roster with the same algo.
Regards https://github.com/profanity-im/profanity/issues/1191
* add theme_hash_attrs()
* when printing a user message check PREF_COLOR_NICK to decide whether
to colorize it or not
ideally we should hash the jid instead of the nick but this is already
a first step.
* add the HSL values of each of the 256 terminal colors
* add color_pair_cache_hash_str()
* move common code to _color_pair_cache_get() helper func
after hashing a string to a color, return the closest matching
terminal color using euclidian distance of the HSL diff vector (this
method was found empirically and seems to work well enough...)
From @xaizek s comment on issue #1235:
```
If the move would cause the window to be off the screen, it is an error and the window
is not moved.
Resize on the other hand doesn't fail like this according to its documentation. So new size needs to be applied first.
```
Big thanks to @xaizek for taking a look at our code and helping us!!

This is encountered when biboumi is used.
Example: `/join #debian-next%irc.oftc.net@biboumi.lebihan.pl`
It seems then time can be null.
g_date_time_format() will not work in this case although time_pref will
not be "off". So let's not call g_date_time_format() in this case. But
treat it like time is set to off.
However message reflection will not work properly with biboumi.
Probably we dont get origin-id.
Fix https://github.com/profanity-im/profanity/issues/1230
https://github.com/profanity-im/profanity/issues/1190 had another issue:
Sometimes servers send multiple </delay> and we just checked the first
one we got and only used it if the 'from' attribute was fitting.
However it could be that we actually wanted the second </delay> element
and there the 'from' would have been right.
So we need to loop through them until we get the one with the fitting
'from'.

Gajim sends \u200E and \u200F for RTL.
It is planned that Gajim stops doing this and uses some GTK feature to
get the same result.
However users expressed the whish that we filter out such characters in
incoming messages before displaying them to make Profanity more robust.
I'm still not sure whether I like the solution because it means a lot of
allocating/deallocating upon every new message.
Fix https://github.com/profanity-im/profanity/issues/1220
The problem is that in _handle_groupchat() we look for
STANZA_NS_STABLE_ID which will result in origin-id or stanza-id.
It seems like prosody servers send origin-id first, so this worked in
all my tests. But actually we cannot be sure of the order.
So far we stopped after the first element was found.
I only found xmpp_stanza_get_child_by_ns() and
xmpp_stanza_get_child_by_name() in libstrophe. But we need a combination
of both.
So I created stanza_get_child_by_name_and_ns() for Profanity. I need to
remember to upstream this to libstrophe later (if they really don't have
such a function).

Before we had `/online`, `/away`, `/dnd`, `/chat`, `/xa`.
These commands are no longer available.
We have `/status set online` etc now.
Before `/status` was used to get the status of a contact.
This now moved to `/status get`.
Regards https://github.com/profanity-im/profanity/issues/1116
`/invite <contact>` became `/invite send <contact>.
`/invites` became `/invite list`.
`/decline` became `/invite decline`.
Accept is still done via `/join`.

Additionally to `/resource titlebar on` we now allow the setting via
/titlebar show|hide resource` since it's about the titlebar.
But makes sense to have it in `/resource` too because there is
`/resource message on|off` too. And this one doesnt have an setting of
it's own.

This doesn't work yet. And I have no idea why.
Weird behaviour:
- start profanity
- type 'ASDF'
- ctrl+arrow down
-> text vanishes (like intended)
- arrow up
-> nothing happens (intended is that the last history item [ASDF]
appears)
- type 'ABC'
- press enter
- arrow up
-> ABC appears
- enter
- type 'UUU'
- ctrl+arrow down
- type 'ZZZ'
- enter
- arrow up
- ZZZ appears
- arrow up
- UUU appears
So in the latter case we added to history and deleted from the input
line and then immediately entered new text and pressed enter, to add
this to the history too.
When we do this the not sent text succesfully was stored in history.
Previously we had `/tls show on|off` to manipulate the UI setting for
the title bar. To decide whether to show TLS info there or not.
This should go into `/titlebar`.
Now we have `/titlebar show|hide tls` for this.

XEP-0184: Message Delivery Receipts, *requires* the id attribute.
Generally this is not the case.
For this reason the id was only present in the DeliveryReceipt struct
since it was only used for XEP-0184.
For https://github.com/profanity-im/profanity/issues/660 XEP-0313 MAM
and https://github.com/profanity-im/profanity/issues/805 XEP-0308 Last Message Correction
we will also need the id.
So in preparation for further work let's move the id to the general
ProfBuffEntry.
We will need to adapt code so that we actually always write the ID if we
receive one.
Profanity sends the same value for both. Other clients might not.
Safe both since we could need them later.
Once we implement Last Message Correction we will need the regular id.
If we override it with origin-id and another client chooses to not use
the same value for id and origin-id then we can't interpret the id sent
with the LMC request correctly.
For OMEMO we had a list with our sent messages.
It was used so that we don't decrypt our own messages in MUCs that come
in via reflection.
Recently for https://github.com/profanity-im/profanity/pull/1209 we
started to use origin-id and use an algorithm so we can detect our own
sent messages via checking origin-id.
Profanity uses the same id for the message ID and origin-id.
With 06f300a42c we added the
message_is_sent_by_us() function.
We implemented XEP-0359 this way to fix
https://github.com/profanity-im/profanity/issues/1201 so that we don't
log our own messages in MUCs twice.
We can now check whether the message was sent by us using this function
and can get rid of the list.
Probably we could also put many parts of the sv_ev_room_message()
function inside (else) part of `if (!(g_strcmp0(mynick,
message->jid->resourcepart) == 0 && message_is_sent_by_us(message))) {`.
Have to look more closely whether any of this needs to be run in case
the message actually comes from us.
Some clients (eg. PSI) are sending the stanzas delimited by whitespace
text nodes, which will fail while looping through the <prekeys/>
children and also print weird errors when iterating through the <list/>
of devices.
When debugging this, I was looking at the XML of Gajim and PSI and first
was somehow confused why Profanity printed "OMEMO: received device
without ID" while the XML looked identical (minus the actual IDs and the
JIDs of course).
However, Gajim was sending the XML without whitespace nodes in between
and PSI did not, so for example the following (with the relevant
whitespace nodes marked with X):
<message type="headline" to="..." from="...">
<event xmlns="http://jabber.org/protocol/pubsub#event">
<items type="headline" node="eu.siacs.conversations.axolotl.devicelist">
<item id="...">
<list xmlns="eu.siacs.conversations.axolotl">
X <device id="..."/>
X <device id="..."/> X
</list>
</item>
</items>
</event>
<delay xmlns="urn:xmpp:delay" stamp="..." from="..."/>
</message>
... would result in three times the "OMEMO: received device without ID"
error, because we actually have three XML text nodes here that obviously
don't have an "id" attribute.
Now since the <list/> children above aren't really a problem and only
annoying, text nodes in the <prekeys/> stanza actually cause
omemo_start_device_session_handle_bundle to return failure.
I've fixed this by explicitly matching the stanza names we are
interested in, skipping everything else.

For now we initialize gtk in tray_init().
Should maybe use a general function and check in tray_init and
clipboard_init whether gtk was already initialized.
Also we initialize mucuser properly.
Now in case of a carbon of a MUC PM we sv_ev_incoming_carbon() which
calls _sv_ev_incoming_plain() and then we log it via chat_log_msg_in()
in there.
But we also get the sv_ev_incoming_private_message() and call
chat_log_msg_in() in there too. So the incoming message get's logged
twice.
If I'm not mistaken MUC PMs have not been logged at all if there was no
other client sending carbons.
This should add MUC PM logging functionality.
We still need to make sure carbons log to the same file.

Change default themes text color
Using "default" instead of white makes the default better readable
when using a black/dark font on white/light background.
May fix#535
So far if one had enabled `/history` and did `/msg somenick` the history
was loaded from file and displayed like this:
```
04-04-17 15:23 - 3/4/2017:
01-01-00 10:30 - me: ....
01-01-00 10:31 - somebody: ....
01-01-00 10:32 - somebody: ....
```
So the first line contained the actual date. But the date used in each
line was always 01-01-2000. This date was for some reason hardcoded.
This commit now actually uses that date to build the proper GDateTime
instead of just printing it.
Fix https://github.com/profanity-im/profanity/issues/922
This caused the bug mentioned in the PR comment:
```
It seems with the changes done here we get a crash in: src/xmpp/message.c message_handlers_init() when looking up handlers: ProfMessageHandler *handler = g_hash_table_lookup(pubsub_event_handlers, curr->data);.
Steps to reproduce:
open Profanity and connect
/autoping set 10
/autoping timeout 10
stop WiFi/connection
wait for Lost connection
restart wifi
/connect
```
So far only with dummy value.
We will need an identifier that we can hash together with a message ID
and put in as the origin-id.
So when we receive message we can unsplit it and see if it was sent from
this client.

ncursesw defines _XOPEN_SOURCE macro via command-line. In particular, it
is defined in ncursesw.pc and extracted via pkg-config. From other side,
Python defines the same macro unconditionally in pyconfig.h. Python-3.x
defines the macro with value different than ncursesw does. In turn, this
causes a warning that the macro is redefined. And warnings are treated
as errors.
Since both entities define the mecro unconditionally, we can't simply
reorder headers as Python developers suggest. So, undefine the macro
just before the <Python.h> to fix this silly issue.
room is either argv[0] or allocated by GString. We have to free memory
in the 2nd case. Replace argv[0] with g_strdup(argv[0]) in order to
make unconditional g_free().
If we get a private message from a user in a MUC profanity shows this
like:
`profanity@roomsASDF.dismail.de/Martin: Hi`
This was so far logged at:
`~/.local/share/profanity/chatlogs/my-account-at-server/profanity_at_rooms.dismail.de/2019_09_04.log` as:
```
10:48:13 - profanity@rooms.dismail.de: Hi
```
So the nickname was not saved anywhere. This is due to us not knowing
whether we got a regular message from user@server.org/resource or a MUC
PM from room@server.org/user.
We now check for `<x xmlns='http://jabber.org/protocol/muc#user' />` and
add the resourcepart to the logging if we get it.
The file will be created at
`~/.local/share/profanity/chatlogs/my-account-at-server/profanity_at_rooms.dismail.de_nick` and look like:
```
23:59:43 - nick: Hi
```
Fix https://github.com/profanity-im/profanity/issues/1184
`sv_ev_room_message()` called `groupchat_log_msg_in()` to log all
incoming MUC messages.
`cl_ev_send_muc_msg()` calls `groupchat_log_msg_out()`.
So messages sent by the user himself was logged two times.
Filter the incoming messages and only log the ones not from our occupant
jid/nick.

This theme color applies to the tab title text of the statusbar tab that
is currently shown.
The (somewhat confusingly named) `statusbar.active` theme color now
applies to all other tabs (before, it applied to all tabs).
Coloring of a tab that is highlighted/has new messages is done as before
using the `statusbar.new` theme color.
The default color is set to `cyan`, and thus causes no visible change
for users -- until modified.
Glib can print error messages to stderr and blocking write freezes
Profanity if the buffer is full. Move stderr to nonblocking mode
in hope that glib will skip printing on EWOULDBLOCK error. In this
case we lose some error messages, but Profanity continues working.
https://gultsch.de/dino_multiple.html mentions CVE-2019-16235, CVE-2019-16236 and CVE-2019-16237.
CVE-2019-16235: Is checking the from in carbon messages. We do that.
CVE-2019-16236: Is checking the from in roster pushes. We do that but
didn't log it yet.
CVE-2019-16237: Is checking the form in MAM messages. We don't support

Profanity uses the node part of a JID as display name for a tab. If such
a JID doesn't contain the node part, Profanity crashes on NULL pointer
dereference.

We call omemo_init() when starting profanity and should have an
omemo_close() at exit.
For now we free the fingerprint autocompleter in there.
Fixes valgrind:

Probably missing copy of body to plain in carbon and privmessage.
Only covers the incoming message path because goal is OMEMO decryption
of untrusted message.
Cover some of the log functions but not all.
Implements feature requested at: https://github.com/profanity-im/profanity/issues/632
So instead of:
/time console set <format>
/time chat set <format>
/time muc set <format>
/time mucconfig set <format>
/time private set <format>
/time xml set <format>
As a short cut the user can do:
/time all set <format>
Excluding statusbar and lastactivity settings since they are not for main windows, but used slightly differently.
Some code was duplicated/similar.
The parts about using a chatwin while being started from another window
(recipient provided) and being a chatwin were the same.
Like this it should be easier to read and less code.
In case Python or C plugins are disabled install/load failed silently.
Notify the user that we can't load them because profanity was built
without support for plugins.
Some of the omemo commands depend on the roster being present.
Several of those functions call `assert()` if that's not the case.
Modify omemo autocompletion in such a way that only things that don't
need the roster will be completed. Only works on first level.
When typing `/omemo` it will still complete to `/omemo start` but not
offer suggestions for that, but print a message that you need to be
connected.
Fix https://github.com/profanity-im/profanity/issues/1117
If re-establish a connection don't print the room history again.
In case there there happened nothing at all since we got the room
history on the last connection.
And in case there were no new messages during the time we have been
disconnected.
Instead of printing the room history again we now print 'Re-established
Connection'.
This adds a bit of overhead since we save the timestamp upon every MUC
message.
