2123ddb425 avcodec: add avpriv_dca_parse_core_frame_header()
There are 3 different places where DCA core frame header is parsed:
decoder, parser and demuxer. Each one uses ad-hoc code. Add common core
frame header parsing function that will be used in all places.

44ac13eed4 dca: fix misaligned access in avpriv_dca_convert_bitstream
src and dst are only 8-bit-aligned, so accessing them as uint16_t causes
SIGBUS crashes on architectures like sparc.

This fixes ubsan runtime error: load of misaligned address for type
'const uint16_t', which requires 2 byte alignment
