ff42991c72 gallium: fix comment again. A half-closed interval was intended. 
Never saw the [a,b[ notation before.

eb4dded5be Mesa: fix number of buffers in st_draw_vbo(). 
The clean-up call to pipe->set_vertex_buffers() should use the same
number of buffers as the first call.

325cbeb29a util: Fix util_fast_pow/exp2/log2. 
- 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: 8415d06d90

This fixes some pow() glitches seen in fslight.c, spectex.c, etc.

2f1a29654a mesa: update the shader programs->TexturesUsed array at link time 
If an application never calls glUniform() to set sampler variable values
they'll remain 0 (the default value/unit).
Now call _mesa_update_shader_textures_used() at link time in case glUniform()
is never called.  program->TextureUsed[] will then be correct for state
validation.

8160cb4935 gallium: fix alignment parameter passed to u_mmAllocMem() 
Was 32, now 5.  The param is expressed as a power of two exponent.
The net effect is that the alignment was a no-op on X86 but on PPC we
always got the same memory address everytime rtasm_exec_malloc() was called.

6d4d51d647 mesa: new _mesa_set_vp_override() function for driver-override of vertex program 
Patch provide by Keith.
Used in state tracker by DrawPixels to indicate that the state tracker (driver)
is using its own vertex program.  This prevents the texenvprogram code from
replacing conventional shader inputs with state vars.
Fixes glDraw/CopyPixels regressions.
