softpipe: rework texture sampling code
Split into component pieces, stitch together at runtime using function pointers. Make it possible to utilize the existing fastpaths as image-level filters for generic mip-filtering routines. Remove special case for rectangle filtering, as it can now be handled by the 2d path. As most of the mesa demo texturing was already covered by fast paths, its harder to find examples of speedups, but tunnel gets a boost as mip-nearest filtering is now able to access the img_2d_linear_wrap_POT functions for sampling within a mipmap level.
