configure.ac defined G_THREAD_SOURCE and gthread-impl would #include it.
Instead, since we only have two thread implementations now, and since we
always use the Windows one only on Windows, move the logic to the
Makefile, predicated on 'if OS_WIN32'. Then have the chosen backend do
the #include "gthread-impl.c" from there.
Remove the G_THREAD_SOURCE define from configure.ac.
In particular, remove the libasyncns import, which was only used by
GUnixResolver, which is only used when threads are not available.
Likewise remove GWin32Resolver, and the hacky broken non-threaded
parts of GIOScheduler.

G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).

We had the 12 hour time format hard-coded to "%02d:%02d:%02d %s" but it
actually changes depending on the locale. Just with the other formats,
use nl_langinfo() if we have it, otherwise fall back on gettext().
- getmntinfo can take struct statfs or statvfs depending on the
OS. Use getvfsstat and if not found getfsstat instead. Idea from
Dan Winship.
- g_local_file_query_filesystem_info(): use statvfs.f_fstypename
if available

Improve a few situations where g_date_time_format() was getting the
padding wrong when displaying alt digits (eg: Arabic numerals) for
formatting time.
We now depend on nl_langinfo (_NL_CTYPE_OUTDIGITn_WC) to do the
conversion, which is very likely glibc-specific, but our previous method
relied on a glibc-specific printf() feature, so no harm done there.
Add a configure check for nl_langinfo (_NL_CTYPE_OUTDIGITn_WC).
Uncomment a few testcases that were failing previously.

Also, link libgio to -lresolv explicitly, rather than depending on
getting it implicitly via the libasyncns build (which should
eventually be going away).

This makes the source efficient on Linux.
Tested on Fedora 15 x86_64 + updates, kernel-2.6.40-4.fc15.x86_64
Also tested fallback code for unsupported flag TFD_TIMER_CANCEL_ON_SET
on kernel 2.6.38.

This makes g_date_time_format() react to LC_TIME, which is
what people expect.
Translators: this change means that the GDateTime strings
are only used when the C library does not already provide
suitable translated strings for these (month names, etc).
We need to test the case of eventfd in the libc but no kernel support.
In order to do that, we add a separate compile of the GWakeup testcase
that interposes an 'eventfd' symbol that always returns -1 with errno
set. That will trigger the fallback case.
- move choice of statfs vs statvfs from gio/glocalfile.c to configure.ac
- if statvfs is the choice, then don't check number of arguments to statfs()
- use choice in gio/gunixmounts.c as well

The Linux eventfd() call is basically tailor made for the main loop
wake up pipe - all we want is a threadsafe way to write to a file
descriptor, and wake up the context on the other end; we don't care
about the content at all.
The eventfd manual page basically explains the benefits:
Applications can use an eventfd file descriptor instead of a
pipe (see pipe(2)) in all cases where a pipe is used simply to
signal events. The kernel overhead of an eventfd file
descriptor is much lower than that of a pipe, and only one file
descriptor is required (versus the two required for a pipe).
When writing my multithreaded spawn test case I actually hit the 1024
file descriptor limit quickly, because we used 2 fds per main context.
This brings that down to 1.

We can use AC_CHECK_FUNCS to detect if qsort_r is available on
the system or not since it will unconditionnally define
HAVE_QSORT_R, which we don't want since on BSD, qsort_r isn't usable
for us, so we don't want to have HAVE_QSORT_R defined on such platforms.
By using AC_CHECK_FUNC instead, we can defer defining HAVE_QSORT_R until
we have actually tested it's usable.

When cross compiling, test programs cannot be run. In order to make it
easier to cross compile for targets that do not have qsort_r(), check
for the function before trying to run the test program.
This avoid having to populate cache with glib_cv_have_qsort_r=no with
e.g. mingw cross compiler.

This avoids the generated types (e.g. ExampleAnimal, ExampleCat,
ExampleObject and ExampleObjectManagerClient) being referenced in the
core gio docs. This was requested by Matthias.

Commit 22e7fc34c4 introduced a regression:
futexes were always disabled and the emulated codepath was always being
used. That commit was in response to an originally buggy
implementationt hat wrote junk into config.h (but happened to be working
properly).
Fix up the mess and while we're at it, close bug #631231 by including
syscall.h from the correct location and using __NR_futex instead of
SYS_futex.
Closes#631231.
