Our fallback realloc path requires an old_size argument, but the posix
varient doesn't need this. Add some code to avoid gcc unused variable
warnings for this extra argument.

The debug functions depend on several util function for os abstractions, and
these depend on debug functions, so a seperate module is not possible.

Unfortunately both Mesa and Gallium use the same defines for memory
allocation (MALLOC, FREE, etc), and worse, some times memory is allocated
with one set and freed with the other set, causing the homegrown memory
debugger to trip on itself.
In the future mesa and gallium should use different names, but for now,
memory debugging on Windows will have to be carried with different tools..

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.

Also, rename p_tile.[ch] to u_tile.[ch]
