c51301db14 dcaenc: move all tables inside context and fix incorrect coding style 
Functionally identical to the old code, with less lines wasted.
Partially fixes the complete disregard for the 80 col/line guide.

56e11ebf55 dcaenc: cleanup on init failure and add a threadsafe init codec cap 
The encoder didn't clean up if a malloc failed during init.
It also doesn't need any external tables to be initialized on init.
Finally, it didn't need to check for whether avctx->priv_data exists during
uninit.

9c4e69b8ea avcodec/dcaenc: Do not abort process in case of bitrate deficit 
Old behaviour - abort if at least one subband has 1bit quantizer
and consumed_bits still greater than frame_bits size. It was
a bit strange - we still could reduce bits consumption by reducing
SNR for other subbands. Same strange logic with upper threshold -
stop bits allocation if at least one subband reach 26bits.

New behaviour - if consumed_bits greater than frame_bits and all
subbands has 1 bit quantizer we restart bits allocation and allow
zero subbands.

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.
