5cfb0a4087 mesa: restore the negate flag of dots in build_lighting. 
Dots is re-used if more than one light is enabled. Previously
the negate flag of dots may affect next light.

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.
