* Represents an immutable reference counted block of memory.
* This is basically the internal glib GBuffer structure exposed,
renamed, and with some additional capabilities.
* The GBytes name comes from python3's immutable 'bytes' type
* GBytes can be safely used as keys in hash tables, and have
functions for doing so: g_bytes_hash, g_bytes_equal
* GByteArray is a mutable form of GBytes, and vice versa. There
are functions for converting from one to the other efficiently:
g_bytes_unref_to_array() and g_byte_array_free_to_bytes()
* Adds g_byte_array_new_take() to support above functions

Add GNetworkMonitor and its associated extension point, provide a base
implementation that always claims the network is available, and a
netlink-based implementation built on top of that that actually tracks
the network state.

Instead of:
warning: ‘g_variant_get_gtype’ is deprecated (declared at ../../gobject/glib-types.h:242): Use '((GType) ((21) << (2)))' instead [-Wdeprecated-declarations]
show:

Also, document the macro-expansion problem in the
G_GNUC_DEPRECATED_FOR docs
Allow passing --identifier-prefix and --symbol-prefix to glib-mkenums,
with the same meanings as in g-ir-scanner, to allow fixing up the enum
name parsing globally rather than needing to add a /<* *>/ override to
each enum.

The documentation for maybe types failed to mention 'a' as one of the
types that was handled with a single pointer for which NULL means
"nothing". Correct that omission.
Problem caught by Shaun McCance.
We clean up the detection of if we should do 'real' atomic operations or
mutex-emulated ones with the introduction of a new (public) macro:
G_ATOMIC_LOCK_FREE. If defined, our atomic operations are guaranteed to
be done in hardware.
We need to use __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 to determine if our
compiler supports GCC-style atomic operations from the gatomic.h header
because we might be building a program against GLib using a different
set of compiler options (or a different compiler) than was used to build
GLib itself.
Unfortunately, this macro is not available on clang, so it has currently
regressed to using the mutex emulation. A bug about that has been
opened here:

Adds g_key_file_ref and g_key_file_unref, to be used by a future

Add functions for manipulating the environment under which a
GAppLaunchContext will launch its children, to avoid thread-related
bugs with using setenv() directly.
FIXME: win32 side isn't implemented yet
https://bugzilla.gnome.org/show_bug.cgi?id=659326
When spawning a child process, it is not safe to call setenv() before
the fork() (because setenv() isn't thread-safe), but it's also not
safe to call it after the fork() (because it's not async-signal-safe).
So the only safe way to alter the environment for a child process from
a threaded program is to pass a fully-formed envp array to
exec*/g_spawn*/etc.
So, add g_environ_getenv(), g_environ_setenv(), and
g_environ_unsetenv(), which act like their namesakes, but work on
arbitrary arrays rather than working directly on the environment.

Some code using GLib (gnome-keyring-daemon, for example) assumes that
they can catch signals by masking them out in the main thread and
calling sigwait() from a worker.
The problem is that our new worker thread catches the signals before
sigwait() has a chance and the default action occurs (typically
resulting in program termination).
If we mask all the signals in our worker, then this can't happen.
With search gaining traction as being the preferred way to locate
applications, the existing .desktop file fields meant for browsing
often produce insufficient results.
gnome-control-center introduced a custom X-GNOME-Keywords field for
that purpose, which we plan to support in gnome-shell as well.

Switch GCond to using monotonic time for timed waits by introducing a
new API based on monotonic time in a gint64: g_cond_wait_until().
Deprecate the old API based on wallclock time in a GTimeVal.
Fix up the gtk-doc for GCond while we're at it: update the examples to
use static-allocated GCond and GMutex and clarify some things a bit.
Also explain the rationale behind using an absolute time instead of a
relative time.
Unlike G_GNUC_... macros, the new G_DEPRECATED[_FOR] are
meant as abstractions that work with different compilers.
Using a new name also lets us restrict it to 'must be placed
before the declaration', which works with more compilers.

Add g_main_context_ref_thread_default(), which always returns a
reffed GMainContext, rather than sometimes returning a (non-reffed)
GMainContext, and sometimes returning NULL. This simplifies the
bookkeeping in any code that needs to keep a reference to the
thread-default context for a while.

Make the options from an /etc/fstab entry available as public API -

All locks are now zero-initialised, so we can drop the G_*_INIT macros
for them.
Adjust various users around GLib accordingly and change the docs.
https://bugzilla.gnome.org/show_bug.cgi?id=659866
Take out the half-private g_private_init() stuff and replace it with a
G_PRIVATE_INIT macro that allows specifying a GDestroyNotify.
Expose the GPrivate structure in a public header.
Add a g_private_replace() to (sort of) match the functionality of
g_static_mutex_set().
Improve the documentation.
Deprecate g_private_new().
Replace it with g_thread_create_with_stack_size() and a real function
implementation of g_thread_create().
Modify a testcase that was calling g_thread_create_full()
inappropriately (it was using the default values anyway).
Create a deprecated/ directory that we can start moving ancient chunks
of code to. Start with GAllocator, GMemChunk and related APIs.
Also drop all mention of them from the docs.

Previously, we were returning an empty buffer for all filenames
where fstat() gives a size of 0. But this is only appropriate
for regular files.

The boolean values to be returned by a GSourceFunc are always ambiguous,
and even in case of experienced developers then can lead to confusion.
The Perl bindings for GLib have two simple constants, mapping to TRUE
and FALSE, that make the return values less confusing: G_SOURCE_CONTINUE
and G_SOURCE_REMOVE respectively.

Only objects and interfaces should go in here. If enums are in here
then gtk-doc responds by outputting two anchors for the same name (which
results in many warnings being printed).
Some links were broken due to typos, because functionality was removed
in GLib 2.0 or for various other reasons. Fix up as many of them as is
reasonable.
Commit ab0e9dbfa7 introduced some changes
to the documentation Makefiles designed to clean-up the process of
deciding which headers get scanned for the docs.
Unfortunately, the gtk-doc Makefile doesn't use HFILE_GLOB for actually
generating the docs -- only for knowing when it needs to redo the
generation. Because of this, we need to use IGNORE_HFILES or otherwise
we get hundreds of symbols in the *-unused.txt files.
Revert the changes that that commit made to the docs Makefiles (but
leave the generation of the *-public-headers.txt files in place).
Change the unix signal watch API to match other sources in both
available functions, names of those functions and order of the
parameters to the _full function.

Several different codebases in GNOME want to implement wall clocks.
While we could pretty easily share a private library, it's not a
substantial amount of code, and GLib already has a lot of the
necessary system-specific detection and handling infrastructure.
Note this initial implementation just wakes up once a second in the
cancel_on_set case; we'll add the Linux-specific handling in a
subsequent commit.
