This is intended to provide a uniform interface for controlling whether
the debug output from an application (or service) is emitted, typically
to journald, but actually to wherever the application chooses to output
it.
The main implementation of `GDebugController` is `GDebugControllerDBus`,
which is intended to be used on Linux. Other implementations may be
added in future for other platforms, or larger applications may want to
provide their own implementation which integrates with their ecosystem.
The `GDebugControllerDBus` implementation exposes a D-Bus interface at
`/org/gtk/Debugging` with a method to enable or disable debug
output at runtime.
This could be used by external harnesses, such as GNOME Builder or
systemd, to give a uniform way to get debug output from an application.

Fixes: #1190
This is an API analogue of the G_MESSAGES_DEBUG environment variable. It
is intended to be exposed outside applications (for example, as a D-Bus
interface — see follow-up commits) so that there is a uniform interface
for controlling the debug output of an application.

On !UNIX, return an error for send_fd() & receive_fd().

The header is now also installed under the common GIO include directory.
Sorry if it breaks any build, you had to use the correct header path.

This function creates a new hash table, but inherits the functions used
for the hash, comparison, and key/value memory management functions from
another hash table.
The primary use case is to implement a behaviour where you maintain a
hash table by regenerating it, letting the values not migrated be freed.
See the following pseudo code:
```
GHashTable *ht;
init(GList *resources) {
ht = g_hash_table_new (g_str_hash, g_str_equal, g_free, g_free);
for (r in resources)
g_hash_table_insert (ht, strdup (resource_get_key (r)), create_value (r));
}
update(GList *resources) {
GHashTable *new_ht = g_hash_table_new_similar (ht);
for (r in resources) {
if (g_hash_table_steal_extended (ht, resource_get_key (r), &key, &value))
g_hash_table_insert (new_ht, key, value);
else
g_hash_table_insert (new_ht, strdup (resource_get_key (r)), create_value (r));
}
g_hash_table_unref (ht);
ht = new_ht;
}
```
Added `g_alloca0()` which wraps `g_alloca()` and initializes
allocated memory to zeroes.
Added `g_newa0()` which wraps `g_alloca0()` in a typesafe manner.
Refreshed and tweaked by Nishal Kulkarni.
Use g_macro__has_attribute to detect it instead of
hardcoding __GNUC__ || __clang__. This adds support
for a few compiler and is consistent with the rest
of the gmacros.h file.
This allows the flag to allow interactive auth to be set. Previously, it
was unconditionally unset.

This allows a pattern like
g_test_message ("cannot reticulate splines: %s", error->message);
g_test_fail ();
to be replaced by the simpler
g_test_fail_printf ("cannot reticulate splines: %s", error->message);
with the secondary benefit of making the message available to TAP
consumers as part of the "not ok" message.

Forming the g_test_skip() message from printf-style arguments seems
common enough to deserve a convenience function.
g_test_incomplete() is mechanically almost equivalent to g_test_skip()
(the semantics are different but the implementation is very similar),
so give it a similar mechanism for symmetry.

g_source_set_name duplicates the string, and this is
showing up as one of the more prominent sources of strdups
in GTK profiles, despite all the names we use being literals.
Add a variant that avoids the overhead.
This should maintain equivalent functionality, apart from that now you
have to pass `--force-fallback-for libpcre` to `meson configure` in
order to use the subproject; rather than specifying
`-Dinternal_pcre=true` to use the internal copy.
This also fixes#642, as the wrapdb copy of libpcre is version 8.37.

On Unix platforms, wait() and friends yield an integer that encodes
how the process exited. Confusingly, this is usually not the same as
the integer passed to exit() or returned from main(): conceptually it's
an integer encoding of this tagged union:
enum { EXITED, SIGNALLED, ... } tag;
union {
int exit_status; /* if EXITED */
struct {
int terminating_signal;
bool core_dumped;
} terminating_signal; /* if SIGNALLED */
...
} detail;
Meanwhile, on Windows, wait statuses and exit statuses are
interchangeable.
I find that it's clearer what is going on if we are consistent about
referring to the result of wait() as a "wait status", and the value
passed to exit() as an "exit status".
GSubprocess already gets this right: g_subprocess_get_status() returns
the wait status, while g_subprocess_get_exit_status() genuinely returns
the exit status. However, the GSpawn family of APIs has tended to
conflate the two.
Confusingly, g_spawn_check_exit_status() has always checked a wait
status, and it would not be correct to pass an exit status to it; so
let's deprecate it in favour of g_spawn_check_wait_status(), which
does the same thing that g_spawn_check_exit_status() always did.
Code that needs backwards-compatibility with older GLib can use:
#if !GLIB_CHECK_VERSION(2, 69, 0)
#define g_spawn_check_wait_status(x) (g_spawn_check_exit_status (x))
#endif

This works in the same way as g_variant_take_ref(), and for the same
reason.

Closes#1112
This adds g_tls_connection_get_protocol_version(),
g_tls_connection_get_ciphersuite_name(), and DTLS variants. This will
allow populating TLS connection information in the WebKit web inspector.
This is WIP because we found it's not quite possibly to implement
correctly with GnuTLS. See glib-networking!151.
