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
Also refactor the function so we pass it the current version
and don't rely on the define inside of it.
This function only allows version format in the style of "x.y.z".
Optimize prof_occurrences by using pointer arithmetic and
g_utf8_next_char instead of calls to g_utf8_offset_to_pointer.
Improve list construction efficiency in prof_occurrences by
using g_slist_prepend and g_slist_reverse instead of appends.
Also fix a slight oversight that could lead to trouble:
When empty search strings (e.g. empty nicks) are passed
it caused matches at every position.
Update the test case to test for empty nicks.
The gpgme_set_passphrase_cb function expects a function
pointer of type gpgme_passphrase_cb_t.
The gpgme_passphrase_cb_t typedef specifies a function that returns
gpgme_error_t so return GPG_ERR_NO_ERROR instead of 0.
Make profanity exit gracefully when it receives either SIGTERM or
SIGHUP. This means that various cleanups will happen as if the user
issued the /quit command, whereas before these signals would terminate
profanity immediately leaving for instance the connection to the server
unterminated.
The main motivation for this change is so that profanity will exit
gracefully when the user closes the terminal that it's running in, which
is a handy shortcut (but can also happen on accident) and won't now lead
to the connection slowly timing out on the server instead. Similarly for
SIGTERM: profanity now for instance needs not be manually closed before
shutting down the computer to avoid the above as it will instead receive
this signal from the init process.
* No need to call `g_key_file_has_key()` before calling a getter.
* Add helper to convert `gcharv` to `glist`.

If one is running multiple instances of profanity, the behavior of the
accounts module was to constantly overwrite the accounts file with the
version that was on-disk of the first instance of profanity started.
This is changed now in order to only write what we modified, we keep a
copy of the accounts file and when "saving" we re-read accounts from disk
and only update the values of the modified account.
This is not 100% fool proof if one modifies the same account from two
different instances, but still better than before.

* Less `GString`.
* Don't `g_free()` a `strdup()`'ed string.
* Don't lookup the `console` window X times, but only once.

* 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 `gchar` instead of `char`.
* improve situations when strings must be duplicated or can pass ownership.
* encapsulate the X.509 name details into a struct.
* prevent memory leaks if a name detail is contained multiple times.

* add can simply do a `memcpy()`.
* in remove we don't have to put the array in a list in order to put it
back into an array again. Also we don't have to `strdup()` each entry,
which leads to even less allocations.
