all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.h
...
The idea is to use ffmath.h for internal implementations of math functions.
Currently, it is used for variants of libm functions, but is by no means
limited to such things.
Note that this is not exported; use lavu/mathematics for such purposes.
