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.

3215342121 avcodec/on2avc: Fix stability issues with scale_tab generation 
This also simplifies the code
the resulting values are binary identical to what pow(10, i/10.0) produces

71af38954b avcodec/on2avc: fix regression on icc since 5495c7f 
Should fix the regression, and also speeds up table generation.
Tables tested on GNU/Linux+clang: they are identical to the ones prior
to 5495c7f. ff_exp10 caused one slight change in one entry, 50000 became
50001 due to somewhat incorrect rounding.

Untested on ICC; passes FATE on GNU/Linux+gcc.

4d5c3b02e9 on2avc: limit number of bits to 30 in get_egolomb 
More don't fit into the integer output.

Also use get_bits_long, since get_bits only supports reading up to 25
bits, while get_bits_long supports the full integer range.
