Ensure that the object has consistent state also when calling the destroy
callback. Namely, ensure the object passed to the callback is removed from

- 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.

These are plug-in fallbacks for the pipe->surface_copy() and
pipe->surface_fill() functions.

We want to use the pipe_buffer_* inlines everywhere, but a pipe context
is not always available nor is it needed.
