The various conformance tests pass now.

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.

* commit 'origin/gallium-0.1':
Mesa: fix number of buffers in st_draw_vbo().
Nouveau: fix nv20_vertex_layout()
Nouveau: update nv20 miptree according to nv40.
Nouveau: build, link and use nv20.
Nouveau: name replace for nv20.
Nouveau: Rename nv20/ files as nv20.
Nouveau: copy nv30_vertprog.c to nv20.
Nouveau: start nv20 by copying the nv10 tree.

Fixed a boneheaded error in the generation of SPU code that calculates
the results of the stencil test. Basically, all the greater than/less than
calculations were exactly inverted: they were coded as though the
given comparison took the stencil value as a left-hand operand and the
reference value as a right-hand operand, but the actual semantics always
put the reference as the left-hand operand and the stencil as the right-hand
operand.
With this fix, tests/dinoshade runs, as do all the other Mesa tests
and samples that use stencil (and that don't use texture formats
unsupported by Cell).

With these changes, the tests/stencil_twoside test now works.
- Eliminate blending from the stencil_twoside test, as it produces an
unneeded dependency on having blending working
- The spe_splat() function will now work if the register being splatted
and the destination register are the same
- Separate fragment code generated for front-facing and back-facing
fragments. Often these are the same; if two-sided stenciling is on,
they can be different. This is easier and faster than generating
code that does both tests and merges the results.
- Fixed a cut/paste bug where if the back Z-pass stencil operation
were different from all the other operations, the back Z-fail
results were incorrect.

Never saw the [a,b[ notation before.

This hack now causes breakage *doh*. :)

- Use a lookup table for log2.
- Compute (float) (1 << ipart) by tweaking with the exponent directly to
avoid integer overflow and float conversion.
- Also table negative exponents to avoid float division and branching.
- Implement util_fast_exp as function of util_fast_exp2.

Cherry-picked from gallium-0.2: 8415d06d90a197e16554dab98d160334fd9f9f93
This fixes some pow() glitches seen in fslight.c, spectex.c, etc.

This allows us to use SSE codegen with debug builds again.
When PIPE_ARCH_SSE is set (w/ gcc -msse -msse2) we will also use the
gcc SSE intrinsic functions.

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.
