Make get_random_string() return a gchar*.
This is part of the effort to migrate string declarations and
allocations from char to gchar, replacing standard C allocators
(malloc/calloc/strdup) with their glib equivalents
(g_malloc/g_new0/g_strdup).
The primary goal is to prevent mismatched allocator bugs. While char and
gchar are binary compatible, mixing their respective deallocators is
dangerous:
* Freeing malloc'd memory with g_free() (or vice versa) can lead to
memory corruption, double-frees, or crashes.
* This is seems to be the case especiall on non Linux platforms or when
using hardened memory allocators where the GLib slice allocator or
wrappers may differ from the system heap.
By standardizing on gchar, we ensure that our automatic cleanup macros
(like auto_gchar) always invoke the correct deallocator (g_free).
* Add new TLS policy `direct` as a replacement for `legacy`.
* Document that `/[command]?` prints the help of a command.
* Add option to get help via `/command help`.
* Fix `my-prof.supp` generation and tests for out-of-source builds.

Use a singleton `Jid` inside the connection instead of always re-creating
a `Jid` from the same string.

Fixup/revert of e55f6d7f4d
This line had been added because an earlier release of libstrophe missed
the initialisation of that variable, which has since been fixed.

Introduce new feature: sessions_alarm.
Added new account setting: max_connections. On exceeding this number,
user will get an alert. If number is less than 1, no alert will happen.
Tests altered to fit new feature.
* save SM state and send-queue entries on disconnect
* restore SM state and send-queue entries on reconnect

* use custom memory descriptor that `abort()`s on `malloc()` failure
* use static log descriptor
* don't always re-create all contexts
* de-duplicate code of `.._connect()` and `.._register()`

In case we're not connected yet and press Alt+c a segfault occurred
since `conn.xmpp_conn` is dereferenced while it's still `NULL`.

Set this to 0.
We might want to have this configurable later.
For now we fix the valgrind report:
```
Conditional jump or move depends on uninitialised value
xmpp_debug_verbose()
```
Which will be fixed in libstrophe > 0.11.0 by commit
