1. Move all GL entrypoint functions and files into src/mesa/main/
This includes the ARB vp/vp, NV vp/fp, ATI fragshader and GLSL bits
that were in src/mesa/shader/
2. Move src/mesa/shader/slang/ to src/mesa/slang/ to reduce the tree depth
3. Rename src/mesa/shader/ to src/mesa/program/ since all the
remaining files are concerned with GPU programs.
4. Misc code refactoring. In particular, I got rid of most of the
GLSL-related ctx->Driver hook functions. None of the drivers used
them.

We were previously calculating a value which was either the geometry
shader output primitive or the application's input primitive, and
passing that to the various front/middle/back components for use as
the ultimate rendering primtive.
Unfortunately, this was not correct -- if the vcache decomposition
path is active and geometry shaders are *not* active, we can end up
with a third primitive -- specifically the decomposed version of the
input primitive.
Rather than trying to precalculate this, just let the individual
components inform their successors about which primitive type they are
recieving.
Any elt may potentially have flags bits set so mask off those bits
everywhere.
Fixes crashes with demos/gamma.c, redbook/polys.c, etc. but polygon
stippling is still broken.
The extension defines eglGetDRMDisplay that creates an EGLDisplay from a
DRM fd. Calling eglCreateWindowSurace or eglCreatePixmapSurface with
such displays will generate EGL_BAD_NATIVE_WINDOW or
EGL_BAD_NATIVE_PIXMAP.
This commit introduces type-safe platform displays internally. A
platform display consists of a generic pointer and an enum that
specifies the platform.
An EGLDisplay is created from a platform display. Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform(). Platform windows and pixmaps may also be
introduced if needed.
Galahad is a sanity-checking layer meant to replace the crufty and
scattered sanity checks inside drivers with a robust, non-silenceable,
useful set of warnings and errors that can be used to keep misbehaving
state trackers from going unnoticed.
This is a follow-on to commit 80dfec3e53.
The valid attachments for glGetFramebufferAttachmentParameteriv() depends
on whether we're querying the default FBO or a user-created FBO.
