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.

This makes probing for regular DTS more strict because more header
fields are checked and values not supported by decoder are now rejected.
Also fixes an issue original code had with 14-bit streams: 96 bits of
header were expected, however only 84 bits were converted, which was not
enough to parse
Permits applications to access DTS profile information without having to
decode a frame.

Parse core frame size directly when searching for frame end instead of
using value extracted from previous frame.
Account for unused bits when calculating sync word distance for 14-bit
streams to avoid alias sync detection.
Parse EXSS frame size and skip over EXSS frame to avoid alias sync
detect
Values for unsupported frequencies > 48000 Hz are still included (parser
will make use of them).
Also convert sampling frequencies array to unsigned.

This requires parsing EXSS in dca_parse(). Adapt ff_dca_exss_parse()
signature and disable header CRC check when avctx->priv_data is NULL.

Move this from separate structure field to a packet flag.
Behavior should be equivalent, except that residual flag is now properly
cleared when packet has no core frame at all.
Also print a message when forcing recovery mode due to invalid residual
to make debugging easier.

DCA core decoder no longer uses fixed tables for channel reordering.
Move them into private encoder header (and drop ff_dca_ prefix).

Limit the maximum length of unary part of Rice code by the number of
available bits instead of using an arbitrary constant that happens to be
just large enough to work.
This effectively limits amount of data that can be overread per segment
by maximum length of binary code per sample multiplied by
The first X96 channel set can have more channels than core, causing X96
decoding to be skipped. Clear the number of decoded X96 channels to zero
in this rudimentary case.
