Now there is just a single, struct __GLXcontextRec, which is the
GLXContext typedef has already been defined as a pointer to. I
believe this is the intended usage, that GLX implementations should
define that struct as they require.
Merge the two previous structs into one and get rid of the
no-longer-necessary type casts and sub-classing.
Using drm_i915_sarea_t instead of struct drm_i915_sarea seems to be
a common standard now, therefore fix it also in intel_context
structure. Additionally this silences a compiler warning:
intel_swapbuffers.c: In function `intelFixupVblank':
intel_swapbuffers.c:48: warning: initialization from incompatible pointer type

This previously was used only for decomposed (POINT/LINE/TRI) primitives,
but for some time a full range of primitives could end up in here.
Fixes trivial/lineloop-clip on softpipe, among others.

Our fallback realloc path requires an old_size argument, but the posix
varient doesn't need this. Add some code to avoid gcc unused variable
warnings for this extra argument.
This is modelled on the nice & easy-to-use facilities we had
for building shaders in mesa, eg. in texenvprogram.c and friends.
Key points include pass-by-value register structs that can be manipulated
in a functional style, eg:
negate(swizzle(reg, X,X,X,X))
and per-opcode instruction functions, eg:
emit_MOV( p, writemask(dst, 0x1), negate(src));
and similar.
Additionally, the interface allows mixed emit of instructions and decls,
which are sorted out internally to obey TGSI ordering.
Immediates may be emitted at any time and are scanned against existing
immediates to try and reduce redundancy.
Not all TGSI functionality is accessible through this interface, but
most or all of what mesa uses should be.
This branch introduces new FRAG_ATTRIB_FACE and FRAG_ATTRIB_PNTC fragment
program inputs for GLSL gl_FrontFacing and gl_PointCoord. Before, these
attributes were packed with the FOG attribute. That made things
complicated elsewhere.
