Extrapolate audio timestamps based on the number of samples demuxed.

Deal with some MXF nastiness involving fractional number of
samples per EditUnit when seeking (the specs handwave this away).

Further fixes from Tomas Härdin.

The old one didn't use segmentation. One uses segmentation in all frame
types (--aq-mode=1), and the other uses all segmentation features, but
only in inter frames (mbgraph).

This disables backward probability updates, which makes the codec more
friendly for frame-level multi-threading.

The original test without a forced idct is still useful since it tests
the switching of the idct algorithm/permutation on x86 with MMX. MMXext
or SSE2. Make sure the test runs only if MMX inline asm is available and
force -cpuflags to all.
Add the required bitexact flag for both tests.

Test sample is made from the sample in Bug-Id: videolan/7411

Some HEVC conformance streams zip on
http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/draft_conformance/
were updated without changing the actual stream. Rename them in FATE
accordingly to make it easier to track future stream updates.

Also remove superseded conformance streams. The conformance streams all

The encoder uses almost none of the mpegvideo infrastructure, only some
fields from MpegEncContext.

The FATE results change because now an all-zero quant matrix is written
into the file. Since it is not used for anything for ljpeg, this should
not be a problem.

This has already been done in eb066a4c,
but the number of frames produced from that file changed due to
timestamps changes since then.

This test selects alternate frames from input.

The element was only being written when the value == 1.  But the default
value of this element is 1, so this has no useful effect.  This element
needs to be written when the value == 0.

Binary search is already attempted in the format-specific seek function,
so the fallback is only reached if binary search failed already.
