`MB_CUR_MAX` looks like a macro, but it's a function call and therefore
creates a VLA. We don't want that.
Also this array being uninitialized created the following Valgrind error

Expected behaviour
When you type
/command
/command
it should be just 1 entry in the history.
Behaviour
All the entries were saved.
Behaviour is changed by introducing check. Before adding to history,
entry now is compared to the last history entry.
When editing multi-line messages or comments everything past the first
newline becomes invisible.
This patch fixes it by substituting a Unicode symbol for "return"
instead of printing the newline as is. On locales where it's not
available single backslash is used instead.
GNU Screen terminal emulator is modelled after VT100, its key bindings
for "application mode" (which profanity enables on startup) can be
seen with this: info screen "Input Translation".
The current code enters an infinite loop if the input string happens
to get an invalid utf-8 sequence somehow. For me it was reproducible
by running profanity in a Screen session and pressing Alt-т (cyrillic
letter).
Fix it the way borrowed from 0501e49623
where mbrlen is used for the same purposes.

Type `>` then press tab or shift tab to autocomplete previous messages,
then type your reply and send message.
Newlines are replaced with newline followed by `> `.
A newline is added at the end so that the user can immediately type a
message without manually adding a new line.
This allows profanity to work without segfaulting from NULL
pointer dereferences when used with NetBSD libcurses.
Basic functionality was tested, there may be more NULL pointer
issues hiding.
- Add NetBSD as a recognized platform without -ldl.
- Allow building with NetBSD libcurses instead of ncurses.
- Portability to NetBSD sh - use POSIX '=' instead of '=='.

sets C99 as standard.
strdup() is not part of C99.
For now set `-D_POSIX_C_SOURCE=200809L` macro to have strdup() in C99.
Using `gnu99` instead would be another option.
We should take more care to use glib functions whenever possible.

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.
