50c466d609 g726enc: use av_assert0() for sample_rate validation 
This should never happen, but the check avoids a divide-by-zero.

6ac34eed54 g726: use bits_per_coded_sample instead of bitrate to determine mode 
This requires some workarounds in the WAV muxer and demuxer. We need to write
the correct bits_per_coded_sample and block_align in the muxer. In the
demuxer, we cannot rely on the bits_per_coded_sample value, so we use the bit
rate and sample rate to determine the value.

This avoids having the decoder rely on AVCodecContext.bit_rate, which is not
required to be set by the user for decoding according to our API.

d405237bae g726: split the init function for the encoder and decoder 
This also allows for not having a decoder close function.

c8d36d254e g726: pre-calculate the number of output samples. 
Allows for checking output buffer size and simplification of decoding loop.

02170990fd cmdutils: Rename read_file to cmdutils_read_file 
This symbol name clashes with a symbol in gnutls, if linking
statically to that library.

45235d69c2 libdirac/libschroedinger: Drop unnecessary symbol prefixes. 
The names used in the libdirac/libschroedinger wrappers are long enough as-is.
Bloating them with unnecessary prefixes makes them even more unwieldy.

44d2a982ac dsicin: fix several audio-related fields in the CIN demuxer 
bits_per_coded_sample should be 8.
block_align is calculated incorrectly, but it is not needed anyway.
packet pts should be calculated in samples.
packet duration can be set.

46e1af3b0f utvideo: handle empty Huffman trees 
If the frame is filled with the same colour, encoder may produce no data
and the fill value is indicated by zero code length (the rest of symbols
will have 0xFF for code length, meaning invalid).  So such Huffman trees
should be treated specially.

4f4e19480a binkaudio: only decode one block at a time. 
This prevents truncating output due to an output buffer that is too small for
all blocks. There is no limit on the number of blocks in a packet.
