[915] Fix COS function using same plan as SIN.

The previous COS function failed badly outside of [-pi/2, pi/2].

[915] Use a quartic term to improve the accuracy of SIN results.

r300 uses.

[915] Fix fp SIN function, and use a quadratic approximation instead of Taylor.
...
The Taylor series notably fails at producing sin(pi) == 0, which leads to
discontinuity every 2*pi. The quadratic gets us sin(pi) == 0 behavior, at the
expense of going from 2.4% THD with working Taylor series to 3.8% THD (easily
seen on comparative graphs of the two). However, our previous implementation
was producing sin(pi) < -1 and worse, so any reasonable approximation is an
improvement. This also fixes the repeating behavior, where the previous
implementation would repeat sin(x) for x>pi as sin(x % pi) and the opposite
for x < -pi.

gallium: add bitmap/drawpixels texcoord bias support
...
The state tracker will call pipe->get_paramf(PIPE_CAP_BITMAP_TEXCOORD_BIAS)
to get a bias factor for adjusting the texcoords used in bitmap/drawpixels.
This allows us to compensate for small differences in rasterization from
one device to another.

[965] Fix TTM relocation caching overzealousness.
...
The failure mode that was a available was:
reloc 1 -> target_buf
exec: PRESUMED_OFFSET wrong, buffer migrates, r1 entry updated.
reloc 2 -> target_buf
exec: suppose buffer migrates again. PRESUMED_OFFSET wrong. r2 entry updated.
reloc 1 -> target_buf
exec: suppose buffer doesn't migrate. PRESUMED_OFFSET right. no relocations
performed. r1 has stale pointer at original location.
Failures were reported with OGLconform's VBO test and SPECviewperf90, though
I haven't confirmed that this fixes it.
