Update a series of error messages to use `g_set_error_literal` instead
of `g_set_error`. This should prevent `format-nonliteral` compiler
issues when `-Werror` is configured:
../gio/gunixconnection.c: In function ‘g_unix_connection_receive_fd’:
../gio/gunixconnection.c:183:9: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
183 | nscm);
| ^~~~
../gio/gunixconnection.c:217:20: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
217 | nfd);
| ^~~
../gio/gunixconnection.c: In function ‘g_unix_connection_receive_credentials’:
../gio/gunixconnection.c:601:24: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
601 | nscm);
| ^~~~
This is similar to a previous change [1] made to `gunixconnection.c`.

Since commit c0ca3f99 this test is strictly depending on GDesktopAppInfo
that is not defined or available in macos, so skip the test as we do for
windows.
We could have done this at meson level too, but keeping it this way is
probably a better reminder that this should be adapted for such scenario
one day™

The merge request !2848 added code to automatically detect the module
prefix on macOS, with a test for the Mac #define TARGET_OS_OSX. However,
older versions of the SDK (at least 10.11) don't provide this #define,
leading to build failure. If the #define is missing, fall back to
checking TARGET_OS_MAC. On newer SDKs this symbol is also true for
watchOS, etc., but in those situations TARGET_OS_OSX is available.
Even though having NULL as nullptr should be the standard for newer C++
versions, it may break some headers, so let's not touch it for now.
Closes: https://gitlab.gnome.org/GNOME/glib/-/issues/2973
Various gio modules include gmodule.h that requires the
gmodule-visibility.h to be already built.
To make this easier, just provide a dependency and use it where we are
building modules that do not depend on libgio_dep (that already includes
that).

The generated gir file marks the size parameter as "out" by default. This is wrong in the context of a caller allocated buffer with a given size. Explicitly marking the size parameter as (in) fixes the issue.
Various projects are running tests under valgrind, and they are using
the GLib suppresions to avoid false-positive results.
While this is stored in a well-known path for some years, and easy to
figure out from the GLib prefix, it's better to expose it through a
proper pkgconfig variable so that it's easy to get it from any build
system.
We were working around that with a call to chdir("."). Internally chdir()
sets up cmd shell-related environment variables, but only if the current
working directory belongs to a volume with a drive letter. For example,
if the current working directory is on a UNC volume like a network share,
the call to chdir() won't help.

Add three classes of test case for which g_utf8_normalize() should
safely return NULL:
- Strings ending with a truncated multibyte character which would
extend past the NUL terminator
- Strings ending with a multibyte character which extends past the
length limit provided by the max_len argument
- Strings containing an invalid multibyte character in any position
_g_utf8_normalize_wc() could read past the end of the provided buffer if
it ends with a truncated multibyte character. If max_len is -1, it can
continue reading until it encounters either a NUL or unreadable
memory. Avoid this with extra bounds checks prior to g_utf8_get_char()
to ensure that it does not read past either max_len or a NUL
terminator.
The ref on the timeout source owned by `SendMessageData` was being
dropped just after attaching the source to the main context, leaving it
unowned in that struct. That meant the only ref on the source was held
by the `GMainContext` it was attached to.
This ref was dropped when returning `G_SOURCE_REMOVE` from
`send_message_with_reply_timeout_cb()`. Before that happens,
`send_message_data_deliver_error()` is called, which normally calls
`send_message_with_reply_cleanup()` and destroys the source.
However, if `send_message_data_deliver_error()` is called when the
message has already been delivered, calling
`send_message_with_reply_cleanup()` will be skipped. This leaves the
source pointer in `SendMessageData` dangling, which will cause problems
when `g_source_destroy()` is subsequently called on it.
I’m not sure if it’s possible in practice for this situation to occur,
but the code certainly does nothing to prevent it, and it’s easy enough
to avoid by keeping a strong ref on the source in `SendMessageData`.

It already implicitly held a strong ref on its `GTask` values, but
didn’t have a free function set so that they would be automatically
unreffed on removal from the map.
This meant that the functions handling removals from the map,
`on_worker_closed()` (via `cancel_method_on_close()`) and
`send_message_with_reply_cleanup()` had to call unref once more than
they would otherwise.
In `send_message_with_reply_cleanup()`, this behaviour depended on
whether it was called with `remove == TRUE`. If not, it was `(transfer
none)` not `(transfer full)`. This led to bugs in its callers.
For example, this led to a direct leak in `cancel_method_on_close()`, as
it needed to remove tasks from `map_method_serial_to_task`, but called
`send_message_with_reply_cleanup(remove = FALSE)` and erroneously didn’t
call unref an additional time.
Try and simplify it all by setting a `GDestroyNotify` on
`map_method_serial_to_task`’s values, and making the refcount handling
of `send_message_with_reply_cleanup()` not be conditional on its
arguments.

This is equivalent to the current behaviour, but a little clearer in its
meaning.
