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.

The main rationale for adding it was to avoid having gnome-shell
mmap'ing /etc/localtime once a second. However, we can just as easily
run inotify there, and given no one else was clamoring for a way to
detect when the time zone changes, I don't see a need for public API
here - at least not yet.
In the bigger picture, I just don't believe that the vast majority of
applications are going to go out of their way to instantiate and keep
around a random GTimeZoneMonitor class. And if they do, it's has the
side effect that for other bits of code in the process, local GDateTime
instances may start varying again!
So, if code can't rely on local GDateTime instances being in a
consistent state anyways, let's just do that always. The
documentation now says that this is the case. Applications have
always been able to work in a consistent local time zone by
instantiating a zone and then using it for GDateTime constructors.
We fix the "gnome-shell stats /etc/localtime once a second" issue by
using timerfd (in glib) and inotify (in gnome-shell).

At the same time, also add g_mkdtemp_full and g_dir_make_tmp
variants. The patch also unifies the unique-name-generating
code for all variants of mkstemp and mkdtemp and adds tests
for the new functions.
Based on patches by Paolo Bonzini,

This implements g_hmac_xxx() functionality using the standard checksum
functions supported by glib.
HMAC is a secure way to hash a key and a password. Many other
approaches fraught with append and prepend issues.
Includes test cases defined in relevant RFCs

This commit changes GLib size units policy. We now prefer SI units and
allow for use of proper IEC units where desired.
g_format_size_for_display() which incorrectly mixed IEC units with SI
suffixes is left unmodified, but has been deprecated.
g_format_size() has been introduced which uses SI units and suffixes.
g_format_size_full() has also been added which takes a flags argument to
allow for use of IEC units (with correct suffixes). It also allows for
a "long format" output which includes the total number of bytes. For
example: "238.5 MB (238,472,938 bytes)".
Add G_VARIANT_TYPE_OBJECT_PATH_ARRAY along with accessor functions
g_variant_new_objv, g_variant_get_objv and g_variant_dup_objv. Also add
support for '^ao' and '^a&o' format strings for g_variant_new() and
g_variant_get().

This function implements the following logic:
if (g_variant_is_floating (value))
g_variant_ref_sink (value);
which is used for consuming the return value of callbacks that may or
may not return floating references.
This patch also replaces a few instances of the above code with the new
function (GSettings, GDBus) and lifts a long-standing restriction on the
use of floating values as the return value for signal handlers by
improving g_value_take_variant().

The function can be used to let regex compile non-NUL-terminated
strings without redesigning the way the pattern is stored in GRegex
objects and retrieved with g_regex_get_pattern.

Rather than having the gtk-doc build machinery have a list of header
files to exclude, change the GLib build to dump a list of public
header files generated from the maintained Makefile.am files for
each of glib/, gobject/, gio/.
Also, for glib, always install glib-unix.h, even on non-Unix
platforms, for the same reason we install gwin32.h even on Unix.

- remove all inline assembly versions
- implement the atomic operations using either GCC intrinsics, the
Windows interlocked API or a mutex-based fallback
- drop gatomic-gcc.c since these are now defined in the header file.
Adjust Makefile.am accordingly.
- expand the set of operations: support 'get', 'set', 'compare and
exchange', 'add', 'or', and 'xor' for both integers and pointers
- deprecate g_atomic_int_exchange_and_add since g_atomic_int_add (as
with all the new arithmetic operations) now returns the prior value
- unify the use of macros: all functions are now wrapped in macros that
perform the proper casts and checks
- remove G_GNUC_MAY_ALIAS use; it was never required for the integer
operations (since casting between pointers that only vary in
signedness of the target is explicitly permitted) and we avoid the
need for the pointer operations by using simple 'void *' instead of
'gpointer *' (which caused the 'type-punned pointer' warning)
- provide function implementations of g_atomic_int_inc and
g_atomic_int_dec_and_test: these were strictly macros before
- improve the documentation to make it very clear exactly which types
of pointers these operations may be used with
- remove a few uses of the now-deprecated g_atomic_int_exchange_and_add
- drop initialisation of gatomic from gthread (by using a GStaticMutex
instead of a GMutex)
- update glib.symbols and documentation sections files
Closes#650823 and #650935
This new API allows watching a few select Unix signals;
looking through the list on my system, I didn't see anything
else that I think it'd reasonable to watch.
We build on the previous patch to make the child watch helper thread
that existed on Unix handle these signals in the threaded case.
In the non-threaded case, they're just global variables.

GLib historically has been designed to be "mostly" portable; there
are some functions only available on Unix like g_io_channel_unix_new(),
but these are typically paired with obvious counterparts for Win32.
However, as GLib is used not only by portable software, but components
targeting Unix (or even just Linux), there are a few cases where it
would be very convenient if GLib shipped built-in functionality.
This initial patch is a basic wrapper around pipe2(), including
fallbacks for older kernels. This pairs well with the
existing g_spawn_*() API and its child_setup functionality.
However, in the future, I want to add a signal() wrapper here,
complete with proxying the signal to a mainloop. I have initial code
for this, but doing it sanely (including factoring out gmain.c's
private worker thread), is a complex task, and I don't want to block
on that.
See also gwin32.h for Win32 specific functionality.
