d12b5b2f13 build: Split test programs off into separate files
This avoids spurious library rebuilds when only the test program
code is changed and simplifies the build system.

db1a642cd2 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.
