Some systems don't provide recent libstrophe releases. When older
version of libstrophe is detected, don't build legacy auth support.
To simplify this patch, report about unsupported legacy auth and
keep commands option as is.
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.

When connection is lost, profanity tries to disconnect what leads
to an infinite loop. The loop occurs, because connection_disconnet()
runs xmpp_run_once() separately and waits for XMPP_CONN_DISCONNECT
event. But it doesn't happen, because the connection object is
disconnected.
As solution, don't disconnect after XMPP_CONN_DISCONNECT is received.
Also, don't free libstrophe objects while the event loops executes,
because the event loop continues using objects after callbacks quit.
New tls policy "trust" added to /connect and /account. With the policy
TLS connection is established even with invalid certificate. Note, that
trust policy forces TLS connection and it fails when server doesn't
support TLS.
Examples:
/connect <jid> tls trust
/account <name> set tls trust
create_unique_id() was changed to use UUIDs instead of a counter in the
last commit. Since now it depends on connection_create_uuid() which is
in the xmpp subfolder the function should also be moved there.
Renamed it to connection_create_stanza_id() and moved it to
src/xmpp/connection.c.
Discussion happened in https://github.com/boothj5/profanity/pull/1010
Add "legacy" tls policy to /account and /connect commands. When this
policy is specified the connection is connected with
XMPP_CONN_LEGACY_SSL flag. Notice, legacy SSL and STARTTLS are not
compatible and user has to know when exactly the new policy should be
used.
To enable it, run one of the next commands:
/connect <jid> tls legacy [server <host>]
/account <name> set tls legacy
Notice, there is no SRV record for legacy SSL. Therefore, you may need
"server" property to connect successfully. Refer to configuration
provided by your server.
