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.

avfilter/af_compand: do not clip; allow >0dB curve points
...
Do not clip output samples, so that clipping can be handled by other filters.
Alow setting curve points above 0dB. This is useful when operating with floats.

af_compand: make sure request_frame always outputs at least one frame
...
This fixes a segmentation fault because request_frame in fifo.c assumes
that the call to ff_request_frame will populate fifo->root.next.
Before, it was possible for request_frame in af_compand to not do this,
resulting in a null pointer access. Now, request_frame in af_compand
always will return at least one frame or an error, as per the API
specifications in avfilter.h for request_frame.
