- ui/window.c win_show_subwin (#1144): unconditional newpad without
freeing the previous pad leaks the ncurses subwin if the function
is invoked twice without an intervening win_hide_subwin. Added a
delwin guard.
- omemo/omemo.c omemo_on_disconnect (#1126): hash tables and
libsignal handles are destroyed unconditionally even when a full
init never ran (e.g. shutdown after a failed load), and neither
g_hash_table_destroy nor signal_*_destroy are documented as
NULL-safe. NULL-check each handle before tearing it down.
- xmpp/roster_list.c (#1140 / #1141 / #1160): null the caller's
pointer immediately after resource_destroy() so a stale reference
cannot trigger a double-free; resource_destroy itself only zeroes
the struct fields it owns and cannot reach back to the caller.
Enable adding oneself to the roster.
Self subscriptions are implicit according to XEP-0060 / XEP-0163.
So we adapt the /sub command to handle this gracefully by just printing
an informative message.
Profanitys logic didn't handle own presence/when adding to roster
correctly. This got fixed now.

Triggered by unit tests. In Profanity itself the situation is probably
rarely happening. We would have to disconnect/exit after receiving
presence but before the roster arrives.
In some cases it was possible that the `roster_pending_presence` list was
not free'd correctly.

The memory leak happens when a presence is received for a MUC room. The
JID is not present in the roster, so updating its status is ignored. We
have to free resource in this case, because it has no owner and is lost
otherwise.

We destory the roster in ev_disconnect_cleanup().
Adding a function to test if the roster has been destroyed and testing
for it in the statusbar.
So now when the connection is lost 'Lost connection' is printed in all
open windows.
We can then reconnect with `/connect accountname`.
Should fix https://github.com/profanity-im/profanity/issues/1083
Presence of contact not found in roster are filtered out.
But sometimes roster is received after a first few presences.
We choose to store presences until we receive roster and then process
this presences.
Fixes#1050
