(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.

functions. Don't allocate the driver-specific data during texture object
creation but do it later as needed (as code originally was).

by calling _mesa_init_driver_functions() and then plugging in the driver-
specific functions.
In particular, make sure ctx->Driver.NewTextureObject points to the
appropriate driver function so that _all_ texture objects are augmented
with the driver-specific data.
Put in a bunch of assertions in the texture-related driver functions that
texObj->DriverData is valid. Remove old dead code in near future.

The def_max_anisotropy option breaks driconf. :( I'm going to upload a
fixed version soon.
