When OMEMO encryption failed due to untrusted devices, the
user was presented with a generic error message. This made it difficult
to identify which specific fingerprints were causing the issue, forcing
users to manually hunt for untrusted keys using /omemo fingerprint.
New function `omemo_get_jid_untrusted_fingerprints` to specifically
identify unverified identities for a contact.
`omemo_on_message_send` will now catch encryption failures and
explicitly list the untrusted fingerprints in the chat window.
Previously the titlebar only showed [OMEMO], regardless of whether the
active session contained untrusted devices. This forced users to manually
run /omemo fingerprint to check the security status of their conversation,
making it difficult to know at a glance if a session was truly secure.
New function `omemo_is_jid_trusted()` to check if all active devices for a JID are trusted.
Update chat and MUC titlebar to display [trusted] or [untrusted] tags when an OMEMO session is active.
Not sure if MUC makes sense here?
Instead of adding stuff to `_shutdown()`, we can now register a shutdown
routine from the respective `init()` function of our modules.
This also has the advantage, that we're sure they're called in reverse
order from how the initialization happened.
I didn't simply use `atexit()` because POSIX says that the number of
possible callbacks is limited (min 32) and I was not sure whether
we will maybe extend this number at one point.

* Fix missing destruction of `session_store` and mutex
* Replace `glib_hash_table_free()`
The glib API `g_hash_table_destroy()` does exactly the same.
* Use the default libsignal `destroy_func` instead of doing that manually
* Set internal state to `0` after everything is cleaned up

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:

There is 3 policy:
- manual: OMEMO session are only started manually
- automatic: OMEMO session are only started if they have been started
manually before
- always: OMEMO session are always started unless they have been ended
manually before
Closes#1040 and fixes#1052
