Use tgsi_sampler struct as a base class. Softpipe subclasses it and adds
the fields it needs.

This is a set of changes that optimizes the memory use of fragment
operation programs (by using and transmitting only as much memory as is
needed for the fragment ops programs, instead of maximal sizes), as well
as eliminate the dependency on hard-coded maximal program sizes. State
that is not dependent on fragment facing (i.e. that isn't using
two-sided stenciling) will only save and transmit a single
fragment operation program, instead of two identical programs.
- Added the ability to emit a LNOP (No Operation (Load)) instruction.
This is used to pad the generated fragment operations programs to
a multiple of 8 bytes, which is necessary for proper operation of
the dual instruction pipeline, and also required for proper SPU-side
decoding.
- Added the ability to allocate and manage a variant-length
struct cell_command_fragment_ops. This structure now puts the
generated function field at the end, where it can be as large
as necessary.
- On the PPU side, we now combine the generated front-facing and
back-facing code into a single variant-length buffer (and only use one
if the two sets of code are identical) for transmission to the SPU.
- On the SPU side, we pull the correct sizes out of the buffer,
allocate a new code buffer if the one we have isn't large enough,
and save the code to that buffer. The buffer is deallocated when
the SPU exits.
- Commented out the emit_fetch() static function, which was not being used.

As suggested by Brian Paul: in the case of a twiddling error, instead
of reporting the bad format number (which is all but unusable), report
the more useful enum name.

Ensure that the object has consistent state also when calling the destroy
callback. Namely, ensure the object passed to the callback is removed from
the table prior to calling the destroy callback to avoid a infinite loop or
double free.

Many stencil tests were failing because of a failure to read the
stencil buffer, due to "twiddling" (or "untwiddling") "an unsupported
texture format". This is fixed for the case of a stencil/Z S824Z format
(which twiddles just like the 32-bit color formats).
tests/stencilwrap.c was failing on the GL_INVERT test, because
the emitted code for "spe_xori" turned out not to be an actual
"xori" instruction, but rather a "stqd" instruction, because
of a typo in the rtasm code. This is now fixed, and
tests/stencil_wrap now works.

The function should update nv20->vertex_info, and not just a
local struct that's thrown away immediately.
Fixes a SIGFPE due to vbuf->vertex_size = 0 in vbuf_alloc_vertices().

No functional changes, only changed function, struct, macro etc. names.
nv10 -> nv20
nv30 -> nv20
celsius -> kelvin
Did not touch fifo command macros.
Don't try to build nv20_vertprog.c for now.
