Janne Grunau 1d01fee980 fix hardcoded tables compililation caused by missing math constants 
Add -D_XOPEN_SOURCE=600 to host cflags to make the constants in math.h
available. Include math.h where necessary and remove redundant M_PI
defines.

Anton Khirnov a50b756280 lavc: remove stats_in from AVCodecContext options table. 
Its documentation states that it is allocated/freed by the caller, but
it is declared as an AV_OPT_TYPE_STRING AVOption. Since
367732832f the AVOptions system frees
strings automatically. This can be considered an API break, since it
won't work when the caller doesn't use av_malloc() to allocate the
memory or wants to use the string after closing the codec.

Since there is not much value in this field being an AVOption, the best
solution is to remove it from the options table.

We generally do not declare variables within for statements and

Kostya Shishkov cac4760bf4 iac: generate codec tables as they are supposed to be 
Unlike its predecessor, Indeo Audio codec generates tables depending on
sampling rate. Previously decoder used pre-generated tables for 22050 Hz
which obviously doesn't work with other frequencies.

Many thanks to Maxim Poliakovsky for providing all needed information
for this.

Kostya Shishkov b56825c40e mpc8: fix maximum bands handling 
In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
frame maximum band limit value.
