Main driver impacts:
- new code for creating the Mesa GLframebuffer
- new span/pixel read/write code
Some drivers not yet updated/tested.

which is automatically generated to match the current texture environment
state. Introduces a new value ctx->FragmentProgram._Active which is
true when either _Enabled is true or there is such a fragment program
ready to run.
To test out on a driver running the software rasterizer, set
MESA_TEX_PROG=t in the environment. It goes without saying that performance
is lower for the software rasterizer in this mode.

- remove input/output fields, input tracking removed.
- remove state fields, the validate function now called
on every statechange.
- add an explicit 'create' function.
Add in code to build vertex program to implement current t&l state. Still
disabled, but turn on with a #define in t_vp_build.h.

Was only used by two drivers to walk over all texture objects. Can do that
via the hash table instead.
Cleaned up some comments for struct gl_texture_object.

which have to be processed in the 'loopback' path. If so, send
all vertices that way as the transition from playback->loopback has
several problems.

no error detection, slow, may not be 100% correct but a good start

Now, the driver's Viewport routine should call _mesa_ResizeBuffersMESA()
if necessary.
Cleaned up code related to GLframebuffer width/height initialization.
Set initial viewport/scissor params in _mesa_make_current2(), instead of
in the drivers' MakeCurrent functions.

(patented) S3TC/DXTC algorithms, but adds an option to dlopen a library module
providing functions to do so. Because it uses dlopen, it is only enabled if
USE_EXTERNAL_DXTN_LIB=1 is defined (which is only in linux-dri config, so far).
It adds support for S3TC to several DRI drivers, and adds a DRI config option to
force enabling S3TC even if the software compression/decompression is
unavailable. This may allow people to use apps that require S3TC even though
they don't have a license to implement the patented material themselves, if
those apps use precompressed textures.
Ideally we would get permission from the current holder of the patents to
implement the algorithm in Mesa, at which point the dlopen mess could go away.
Until then, this allows some to run applications they couldn't otherwise, and
hopefully will provide us with more push to get the final step of getting that
permission done.

Added a DeletePending flag to texture object struct to fix that.
Other misc clean-ups.

program is enabled AND the currently bound program is valid.
Check _Enable instead of Enable to prevent things from blowing up
when someone calls glEnable(GL_VERTEX_PROGRAM_ARB) without actually
defining a program.

The gl_texture_format struct now has a StoreTexImageFunc that's called
by glTex[Sub]Image[123]D to convert the user's texture data into the
specific texture format layout. Now it's much easier to add new texture
formats (like the 16/32-bit floating point formats).
The texutil.[ch] and texutil_tmp.h files are obsolete.

Some need to be set per-vertex, other per-primitive. Cleared that up.
Only need to init temp/result registers if executing an NV vertex program.

and execute fragment programs. Very limited and experimental, but works
well enough to run arbfplight.c.

Compile with 'make linux-tcc', being sure to make clean first.

Only available with Xlib driver for now.
Assorted clean-ups related to Draw/ReadBuffer().
Renamed FRONT_LEFT_BIT -> DD_FRONT_LEFT_BIT, etc.

Note: extension may not be finalized yet - subject to change!
Note: implementation not fully suitable for h/w implementation yet.

IMAGE_CLAMP_BIT if needed.
Added ClampVertexColors and ClampFragmentColors to GLcontext in anticipation
of upcoming extensions (not fully used yet).
