The libmount code produces somewhat different results than the older
Linux code that would parse /proc/mounts; for example, bind mounts
appear in the libmount output. To try and get as many GLib users
as possible to have the same behavior, on Linux, make GLib error out
on missing libmount unless --disable-libmount is passed.

This is causing trouble with flatpaks because the org.gnome.Platform
runtime does not bundle libmount, while the org.gnome.Sdk does it.
As this probably requires a change in the freedesktop.org Yocto base,
we disable this support by default for now as a temporary measure
until it can be properly reviewed by someone who knows those bits
better, probably Alex Larsson.

Talk to the journal ourselves using sendmsg() instead of linking
against libsystemd for sd_journal_sendv(). At the same time, we
can also avoid excessive copying.
The motivation for dropping the dependency is that we can
then use structured logging e.g. in a flatpak sandbox where
libsystemd may not be present in the runtime.
The code here is inspired by similar code in libvirt.
In parallel with g_log(), add a new structured logging API, based around
g_log_structured() and various helper functions which are exposed
publicly to allow programs to build their own logging policies easily,
without having to rewrite a lot of gmessages.c because it’s all
internal.
See the expanded documentation at the top of gmessages.c for some
rationale. See the g_log_structured() documentation for some example
code.

Add filesystem attribute to detect remote filesystems in order to
replace hardcoded filesystem types in GtkFileSystem. Set this attribute
also for GLocalFile appropriately.
Bump version to 2.49.3, so that early adopters of new API have a version
number to target.
We now prefer pthread_setname_np when available, and don't
need the linux specific API anymore. Also change the test
for this functionality to use pthread_getname_np.
The current statfs() compilation tests all fail because statfs() expects
the first argument to be non-null. Pass a dummy path instead of NULL to
satisfy the compiler.

... from glib-gen-srcs.[vsprops|props].in to
glib-version-paths.[vsprops|props].in, and instead let autotools generate
glib-version-paths.[vsprops|props] rather than
glib-gen-srcs.[vsprops|props], as this will need to be referenced for
other items as well, namely generating the .pc files which will become
useful for introspection builds.
Rather than calculating it at configure time. This means it can expand
$libdir properly, and use the Make $(realpath) function rather than
invoking the non-portable `readlink -f`.
This fixes problems where `readlink` would be called on an invalid path
(due to a variable not being expanded) and would evaluate to "", which
would then cause things to be installed in the wrong place.

This causes several problems:
- Compilation in FreeBSD with --enable-gtk-doc broke
- Modules that still use the AM_GLIB_GNU_GETTEXT macro
doesnt compile anymore because /usr/share/glib-2.0/gettext
is not filled with the correct files, as this was done in
the glib custom po/Makefile.in.in

This reverts commit e5c752371c.
Bug 13403 introduced support for the non-POSIX variants of these APIs
found on a system called "DG/UX". Meanwhile, the complicated checks
here are breaking cross-builds on systems that we actually care about.
Remove the complicated checks and replace them with AC_CHECK_FUNCS.
Remove the resulting dead code from a couple of .c files.

Commit 212e4232e7 introduced a big update
of gnulib. Necessary changes to configure.ac from old gnulib commit
e8e63d1b31bca6c82713cba490b21a861abb24b5 have been forgotten. Actually
available functions are not discovered by autotools.

This example has been causing on-and-off build breaks for quite some
time. In this case, the code for copying the generated content into the
main docs of GIO is causing problems with srcdir != destdir builds (due
to the files also being copied from the read-only srcdir during
distchecks).
We could probably work around this problem yet again, but since there is
no real benefit to having this content included, so let's remove it.

It's been a long time since we've been unconditionally saying "static
inline" in GLib headers without complaints so it's safe to assume that
all compilers that we care about support this.
One thing that is not yet totally supported is the unadorned use of the
word "inline". Depending on the flags (-std=c89, for example), even GCC
will complain about this. Detect missing C99 support and define
"inline" to "__inline" in that case. Some research shows "__inline"
appears to be the most widely-supported keyword here, but we may need to
tweak this if we get some reports of breakage.
Clean up all of the configure checks around this and define G_CAN_INLINE
unconditionally. Unfortunately, we must assume that some people are
still using G_IMPLEMENT_INLINES, we must continue to implement that
(including undefining G_CAN_INLINE and redefining G_INLINE_FUNC) if
requested.
It is not our intent to break existing users of the old-style
G_INLINE_FUNC approach and if that has happened, we may need to make
some further adjustments.

It's a platform-specific macro, so it belongs in glibconfig.h.

Now that we initialize the quark tables from a constructor,

Add support for receiving multiple messages with a single system call,
using recvmmsg() if available. Otherwise, fall back to looping over
g_socket_receive_message().
This adds new API, g_socket_receive_messages(), and corresponding unit
tests.

Add a check to configure.ac for strerror_r, since we don't currently
require POSIX.1-2001 conformance in general. Add back a
plain-strerror() case as a fallback, and rearrange the glibc-vs-POSIX
strerror_r() branches.
Update the docs to not claim that "not all platforms support the
strerror() function" (we require C90), but still mention the UTF-8 and
always-valid-string benefits. (And make test_strerror() check that
last part.)

This "adds" the Visual Studio 2015 Project files by doing what we did
before: copying the Visual Studio 2010 projects and replacing items
in them, as the formats of the Visual Studio 201x projects are largely
the same.
Use a simple all-purpose utility script to generate the glib-mkenums
PERL script with the version info, and stop using the script that
tries to parse the autotools files. Move the things that
were taken out from build/win32/setup.py back there.
We don't need to run binaries we just built in order to successfully
build GLib and friends any more.
Since commit b74e2a7, we don't need to run glib-genmarshal when building
GIO; since commit f9eb9eed, all our tests (including the ones that do
need to run binaries we just built) are only built when running "make
check", instead of unconditionally at every build.
This means that we don't need to check for existing, native binaries
when cross-compiling, and fail the configuration step if they are not
found — which also means that you don't need to natively build GLib for
your toolchain, in order to cross-compile GLib.
We can also use the cross-compilation conditional, and skip those tests
that require a binary we just built in order to build.

AC_C_BIGENDIAN can return 'universal' as the result in the case that we
are trying to do a universal build on Mac OS. This has to be opted into
explicitly by using multiple -arch CFLAGS.
Previously, we detected this result and fell back to doing our own check
based on the endianness of the build machine, hardcoding that. This
means that universal builds might successfully build, but the binaries
would never actually run correctly on the 'opposite' arch.
This check was added because of a bug in the intial implementation of
this detection in autoconf, which was inappropriately identifying
non-macos compilers as 'universal'. That was hitting ppc64 systems.
See https://bugzilla.redhat.com/show_bug.cgi?id=449944 for more info.
Commit b0e687ef42e21b1eb7af18c4eaebcd41b0bd5632 in autoconf ("Limit
AC_C_BIGENDIAN univeral checks to Mac OS X") solved this issue in 2008,
so let's remove our workaround. For good measure, if we detect
"universal" in the result, error out.

We were using AC_LANG_PROGRAM to build a program to test for our ability
to call syscall (__NR_futex, ...);. This macro adds "main () { ... }"
around the provided code segment automatically. The provided code
segment provided its own main() function, however.
The result looked something like:
int main (void) {
int main (void) {
...
}
}
which worked on GCC, but not on clang.
Let's fix that. Let's fix the same mistake copied over for eventfd()
detection while we're at it.
Like the Visual Studio 2012 project files, the Visual Studio 2013 files are
largely the same as the Visual Studio 2010 project files, so support
Visual Studio 2013 by updating the autotools scripts that is used for
Visual Studio 2012. This means that project files for Visual Studio 2012
and Visual Studio 2013 can be maintained by simply maintaining the Visual
Studio 2010 project files, adding minimal maintenance overhead.
On OpenBSD, libintl is installed under /usr/local/lib. When configure
checks unset LDFLAGS, LIBS should also be unset otherwise we end up with
-lintl which cannot be found resulting to the compile check to fail.

Since the type system does not support reloading its data and assumes
that libgobject remains loaded for the lifetime of the process, we
should link libgobject with a flag indicating that it can't be unloaded.

We've had a relatively rocky path with g_cond_wait_until() on systems
that either don't support pthread_condattr_setclock() or where
g_get_monotonic_time() is not based on CLOCK_MONOTONIC (ie: Android and
Mac OS).
Fortunately, both of these platforms seem to share
pthread_cond_timedwait_relative_np() which allows us to implement
g_cond_wait_until() without races.
With this patch, we now require that one of pthread_condattr_setclock()
or pthread_cond_timedwait_relative_np() exists. A quick look around
suggests that this is true for all platforms that we care about.
This patch removes our use of pthread_cond_timedwait_monotonic() and
pthread_cond_timedwait_monotonic_np() which were Android-only APIs.
https://bugzilla.gnome.org/show_bug.cgi?id=673607
We now assume the existence of clock_gettime() and CLOCK_MONOTONIC as
specified by POSIX.1-2001. This means that we always return truly
monotonic time, which will prevent problems in the case that the user
changes the time.
Mac OS doesn't have clock_gettime() but it does have
mach_absolute_time(), so we can use that there.
We keep our Windows case as well (although we should simplify it once XP
hits EOL later this year).
This patch removes the fallback to gettimeofday() in case of missing
clock_gettime(). We no longer have any way to test this codepath and
therefore it must go.
This patch also restructures the #ifdef a bit so that we repeat the
entire function definition inside of #ifdef instead of just the entire
body of one function.

Our check for inotify_init1() being defined is broken. We happily
declare that inotify is supported, even if the check fails.
This was originally intended to check for inotify_init1 in the libc so
that we could fall back to inotify_init if it was not yet defined.
FreeBSD has a libinotify that emulates the inotify API via kqueue. It
installs a <sys/inotify.h> header and requires linking to -linotify. We
don't want to falsely detect working inotify in this case.
Treat the lack of inotify_init1() in the libc as a lack of inotify
support. This requires only a new libc -- we still support old kernels:
in the case that inotify1_init() fails, we fall back to inotify_init().
https://bugzilla.gnome.org/show_bug.cgi?id=724330
When the function in the test program is inlined, all bets are
off whether the detection will work correctly or not. Make it
harder for the compiler to play games on us by making the
function recursive.
