gallium: Provide alternative stdint.h and stdbool.h C99 headers, instead of ad-hoc definitions.
Everybody is using the C99's integer types. Everybody except Microsoft,
which in turns means everybody is including their own definitions of C99
integer types for MSVC, causing duplicate definitions when linking two
projects. This is the case of building Gallium and LLVM with MSVC.
Shipping alternative stdint.h and stdbool.h headers for MSVC allows us
to share a single definition. It also removes clutter from the Gallium
headers.
Add event support for the GLX swap buffers event, along with DRI2 protocol
support for generating GLX swap buffers events in the direct rendered case.

Support the new DRI2 protocol request, DRI2SwapBuffers, in both direct
and indirect rendering context. This request allows the display server
to optimize back->front swaps (e.g. through page flipping) and allows us
to more easily support other GLX features like swap interval and the OML
sync extension in DRI2.

glut: Silent the glut*_ATEXIT_HACK defined but not used warnings.
There are two ways to silent this: put inline keyword, or reimplement the
hack as a #define. inline keyword actually varies slightly with compiler
so I've opted by the latter.
Commit d33c315d9e removed a few too many
typedefs. We need the typedefs in glext.h which are protected by #ifdef
GL_VERSION_1_2 but we can exclude the ones protected by
GL_VERSION_1_2_DEPRECATED.
Here is a couple of fixes for GNU/Hurd:
- dri_interface.h: no libdrm support either.
- configure.ac:
- GNU/Hurd is a GNU OS with _GNU_SOURCE and PTHREADS.
- GNU needs a couple of flags like other OSes

Fix DRI2 accelerated EXT_texture_from_pixmap with GL_RGB format.
This requires upgrading the interface so that the argument to
glXBindTexImageEXT isn't just dropped on the floor. Note that this only
fixes the accelerated path on Intel, as Mesa's texture format support is
missing x8r8g8b8 support (right now, GL_RGB textures get uploaded as a8r8gb8,
but in this case we're not doing the upload so we can't really work around it
that way).
Fixes bugs with compositors trying to use shaders that use alpha channels, on
windows without a valid alpha channel. Bug #19910 and likely others as well.

glut: Use a new define GLUT_STATIC to distinguish static builds.
_DLL is defined by MSVC when building against a DLL version of the CRT
library. It bears no relation to whether we are building a DLL or not. That
is, we can build a DLL against a static CRT, or a static lib against a
dynamicaly linked CRT. See more detail at
http://msdn.microsoft.com/en-us/library/2kzt1wy3.aspx
This gets DLL version of glut linking correctly both with MinGW and MSVC.
PS: GL/gl.h (and others) must be fixed too.
Trying to override windows headers is a recipe for disaster. Especially
when using with glew. Also the windows headers in recent MinGW are complete
enough that they don't need patching up.
