Silences pointless error message when decoding DTS-in-WAV stream with
excessive frame size stored in header.

Fixes regression introduced by commit a0349ae2
when parsing 14-bit streams with excessive frame size stored in header.

Fixes ticket #6723.

This reverts commit c2d155e1.

GCC 6 incorrectly passes the configure test and then logs many warnings
of the form:

src/libavformat/dump.c: At top level:
cc1: warning: unrecognized command line option ‘-Wno-bool-operation’

Uses vaExportSurfaceHandle() from libva2.

The initialisation should be common.  For libmfx, it was previously
happening in the derivation function and this moves it out.  For VAAPI,
it fixes some failures when deriving from a DRM device because this
initialisation did not run.

The message callbacks are library-safe in libva2, so we can now use
them.

This was duplicated between normal device creation and creation by
derivation from a DRM device.

This is an ABI change in libva2: previously the Intel driver had this
behaviour and it was implemented as a driver quirk, but now it is part
of the specification so all drivers must do it.

This has been deprecated in libva2 because hardware does not and will not
support it.  Therefore never consider it for decode, and for encode assume
the user meant constrained baseline profile instead.

Since af1761f7 ffmpeg waits for a frame in each
stream before writing the output header. If we are using threaded decoding for
attached pictures, we have to read till EOF to be able to finally flush the
decoder and output the decoded frame. This essentially makes ffmpeg buffer all
non-attached picture packets, which will cause a "Too many packets buffered for
output stream" eventually.

By forcing single threaded decoding, we get a frame from a single packet as
well and we can avoid the error.

Fixes part of ticket #6375:
ffmpeg -i 46564100.mp3 -acodec libmp3lame -ab 128k -ac 2 out.mp3

Allows to specify the action to be performed when reading the last frame
from the internal FIFO buffer. By default the last frame is written to
filter output depending on the timestamp rounding method. When using
"pass" action the last frame is passed through if input duration
has not been reached yet.

Examples using an input file with 25Hz, 1.4sec duration:
 - "fps=fps=1:round=near" generates an output file of 1sec
 - "fps=fps=1:round=near:eof_action=pass" generates an output file of
   2sec

These changes store id3 chapter data in ID3v2ExtraMeta and introduce
ff_id3v2_parse_chapters to parse them into the format context if needed.

Encoders using ff_id3v2_read, which previously parsed chapters into the
format context automatically, were adjusted to call
ff_id3v2_parse_chapters.
