When using gcc builtins for atomic operations, provide them
as macros, so gcc can see the builtins and do optimizations.
This change gives considerable speedups in bitlocks, which
use atomic operations heavily, see bug 650458.
Also, don't define G_ATOMIC_OP_MEMORY_BARRIER_NEEDED unconditionally
when using gcc builtins.

_GNU_SOURCE must be defined before including any other (system)
header, so defining it in glib-unix.h (and hoping no one has included
anything else before that) is wrong. And the "#define _USE_GNU"
workaround for this problem in gnetworkingprivate.h is even wronger
(and still prone to failure anyway due to single-include guards).
Fix this by defining _GNU_SOURCE in config.h when building against
glibc. In theory this is bad because new releases of glibc may include
symbols that conflict with glib symbols, which could then cause
compile failures. However, most people only see new releases of glibc
when they upgrade their distro, at which point they also generally get
new releases of gcc, which have new warnings/errors to clean up
anyway.

autoconf 2.68 is very insistent that AC_LANG_SOURCE/AC_LANG_PROGRAM
must be used in certain places, to avoid quoting/lack-of-quoting
problems, or something. Fix.
These are the updates to the autotools files to
ensure the expansion of the GIO, GLib and GObject
project files (*.vcxproj, *.vcxproj.filters) and to
enable the distribution of the VS2010 project files
The actual VS2010 project files will follow shortly
Remove some code that was written in 2000 to support OSes that do not
have nanosleep(). nanosleep() has been specified (in POSIX-1.2001) for
almost a decade now, so assume we have it (except on Windows).
Remove the checks for nanosleep and nsleep from configure.ac.
We're removing this code because we honestly believe that nobody will be
affected. If this change negatively impacts you, please file a bug.
These macros should be used instead of -I for things in the tree that
depend on various bits of glib.
