This reverts commit 6a40d1e9d9.
Turns out that we *do* need these for OQ after all. Go figure.

Move some fields of _EGLDriver to _EGLDisplay. It also becomes
unnecessary to pass _EGLDisplay to drivers when _eglMain is called.

The motivation is so that drivers do not need to look up and check for
bad display, context, and etc. It also becomes unnecessary for drivers
to call the link functions.
This commit makes eglapi.[ch] do the lookup and check. As a result, the
driver API is overhauled, and almost all sources and drivers need
update. The updates are mainly find and replace with human brains.

It's the front stencil methods that have contiguous offsets,
not the back ones.
Unfortunately the names in the header still have FRONT/BACK
reversed, so I'm using hex values until it gets updated.
The TEX instruction is passed the first index of a contiguous
range of 4 TEMP registers that contain coordinates / LOD and,
after execution, the texel values.
It seems the first index is required to be a multiple of 4 on
some (older ?) cards.
This prevents the driver from discarding a buffer when the whole buffer
is mapped for writing, but only a portion is effectively written.
This is a temporary fix, because WRITE shouldn't imply DISCARD.
The full fix implies using PIPE_BUFFER_USAGE_DISCARD, throughout
the code, and will go only into master.
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.
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.
