a969a914f5 dca_parser: ensure frame duration matches the actual sample rate
The parser only parses the core, and thus has a duration relative
to the core sample rate only, not the actual stream sample rate.

FATE references changed due to now correct timestamps.

00ae5b401b dca_parser: don't overwrite the sample rate, it may not be correct
The parser only reads the dca core sample rate, which is limited to a
maximum of 48000 Hz, while X96 and HD extensions can increase the sample
rate up to 192000 Hz.

This change prevents the parser and decoder fighting over the sample rate,
potentially confusing user applications. This also fixes sample rate
display of >48000Hz files with ffmpeg/ffprobe when using libdcadec.

Fixes ticket #4397

0670acc4f1 dca_parser: Extend DTS core sync word and fix existing check
The previous version checked for 14-bit streams and did not properly
work across buffer boundaries.

Use the 64-bit parser state to make extended sync word detection work
across buffer boundary and check the extended sync word for 16-bit LE
and BE core streams to reduce probability of alias sync detection.

Check extended sync word for 16-bit LE and BE core streams to reduce
probability of alias sync detection. Previously sync word extension was
checked only for 14-bit streams (and this check did not properly work
across buffer boundary).

Use 64-bit parser state to make extended sync word detection work across
buffer boundary.

This is sufficient to make the sample in ticket #4492 parse
successfully.

022d22e581 Fix a regression in the dca parser introduced by dts express support.
The dca parser needs to check that the framesize is actually of a complete
frame, and not of a partial DTS-HD frame, which is not constant size, and
thus the check would fail.
