Fix visual glitch with XvMC, caused by wrong idct permutation.
In the past XvMC forced simple_idct since
it was using FF_IDCT_PERM_NONE.
However now we have SIMD variants of simple_idct that
are using FF_IDCT_PERM_TRANSPOSE and if they are selected
XvMC would get coefficients in the wrong order.
The patch creates new FF_IDCT_NONE that
is used only for this kind of hardware decoding
and that fallbacks to the old C only simple idct.

libavdevice/decklink: add support for 10-bit output for Decklink SDI
Can be tested via the following command:
./ffmpeg -i foo.ts -f decklink -vcodec v210 'DeckLink Duo (1)'
Note that the 8-bit support works as it did before, and setting
the pix_fmt isn't required for 10-bit mode. The code defaults to
operating in 8-bit mode when no vcodec is specified, for backward
compatibility.

libavdevice/decklink: add support for -sources and -sinks arguments
Add support for enumerating the sources/sinks via the ffmpeg
command line options, as opposed to having to create a real pipeline
and use the "-list_devices" option which does exit() after dumping
out the options.
Note that this patch preserves the existing "-list_devices" option,
but now shares common code for the actual enumeration.

ffmpeg: always use single threaded decoding for attached pictures
Since af1761f7b5b1b72197dc40934953b775c2d951cc 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

movenc: take packet dts shifting into mention in check_pkt
This FFmpeg-specific "fuzzer fix" was never perfect, but now it
stopped encoding of actual content with a big enough DTS shift.
This returns the function to its original state of results
before negative CTS offsets were added.
I remember dealing with this function before, but somehow had
forgotten about it during VDD. The test cases not tripping this
over also didn't help.
