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).
Migrate structure allocations from calloc to glibs g_new0 macro to
improve type safety and memory robustness.
* Type Safety: The macro takes the type name directly, ensuring the
allocated size always matches the pointer type.
* Static Analysis: It guarantees a non-NULL return by aborting on
failure, which silences -fanalyzer warnings regarding potential NULL
pointer dereferences.
* Readability: Removes redundant sizeof() calls and is the glib way
* 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.

Several users have reported segfaults when starting up profanity which
has OMEMO support, but OMEMO is not set up yet.
@StefanKropp has been able to reproduce this and tracked it down to
`_load_identity()` calling `omemo_known_devices_keyfile_save()`.
The latter then calls `save_keyfile()` which calls
`g_key_file_save_to_file()`. This can then fail if one of the first two
strings is NULL and won't set the `error` on return. In its error handling
`save_keyfile()` unconditionally dereferences `error` which leads to the
segfault.
Fix this and also go through the entire codebase and verify that the usage
of `GError` is done correctly.

We must only return early in cases where we received a roster push with
1. a `from` attribute
2. that `from` is not our bare JID
The server sends roster pushes without `from` attribute and we must accept
them.

While trying to get the unit tests working again I stumbled over all those
things that I thought could be better^TM.
Now we also know "TODO: why does this make the test fail?" - because
the unit tests are brittle AF ... and we have to init the subsystems
we use in the test, otherwise the cleanup will fail...
BTW. you can now also only run a single test ... or a pattern or so ...
you'd have to read how `cmocka_set_test_filter()` works exactly.

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.

In the documentation of the `muc_nick` function we can read:
> The nickname is owned by the chat room and should not be modified or freed
We should reflect that in the return type and `strdup` the value for the
plugin API.

Feature discovery was marked as finished once we received a reply to the
initial request. The discovery mechanism allows to delegate the real
feature discovery to another service running on different domain and those
requests are created dynamically.
This was another instance causing the warning message described in #1940Fixes#1940 (once more)

Reset the `received_disco_items` flag when initializing the iq module.
This has caused the console error message "Server doesn't support MAM"
sometimes on reconnect.

Before this patch the following scenario lead to a segfault:
1. open a window that sends a MAM request
2. fast enough close that window again before the MAM response was
processed
Once the MAM response is received we'd call `_mam_rsm_id_handler()`
from the `_iq_handler()` and `window` would point to a non-existant window
which leads to a segfault.

Disallow correcting historical MUC messages, as the XEP-308 requires.
Previous changes introduce problem with
"Illicit LMC attempt from conference@server/user for message from user"
During investigation it was revealed that XEP does not recommend support
of historical MUC messages correction.
```
When used in a Multi-User Chat (XEP-0045) context,
corrections must not be allowed (by the receiver)
for messages received before the sender joined the room -
particularly a full JID leaving the room
then rejoining and correcting a message SHOULD be disallowed,
as the entity behind the full JID in the MUC may have changed.
