* 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

Remove support for libsignal-protocol-c < 2.3.2.
Debian 10 uses 2.3.2, Debian 11 and 12 use 2.3.3.
openSUSE from 15.2 onward uses 2.3.3.
Fedora since 28 uses 2.3.2.
We should be good.
The most loggings has been set to debug. Just in case of error / problem the
logging should be done with log-level ERROR or WARNING.
We will see later, which loggings should be switched to log-level INFO.
This improvement has been done to find OMEMO bugs.

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.
When decrypting first message with prekey, libsignal wants to remove
used prekey from storage. Return value on success should be 0.
We used to return number of deleted keys. Thus libsignal was considering
we failed to remove the key and we were ignoring plaintext.
