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.

FreeBSD and NetBSD have field st_birthtim and st_birthtime in struct stat,
respectively, which can be used to get file creation time on supported file
systems such as UFS2 and tmpfs.

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.

Allows sending of multiple messages (packets, datagrams)
in one go using sendmmsg(), thus drastically reducing the
number of syscalls when sending out a lot of data, or when
sending out the same data to multiple recipients.

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.

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().
