bad42e9b40 lavf/dashenc: pass standards compliance value to the internal context 
Enables one to test possibly nonstandard formats such as Opus or
FLAC in ISOBMFF, among other things.

This becomes much more useful if output segment format becomes an
option, or if the WebM segment feature gets removed.

48684d2605 lavf/dashenc: require experimental mode to be enabled for WebM 
It has not ever been working and has not been validated,
Additionally, mention that the segment file names should be changed
to end with webm instead of m4s, which is utilized for ISOBMFF
fragments.

e07b1913fc fate/cbs: Always overwrite output in cbs fate tests 
Before this, a failed test would keep failing because the output file
is not cleaned up and subsequent runs would refuse to overwrite it.

ddd3a209dc lavc/cbs: Add tests for VP9 
Uses the same mechanism as other codecs - conformance test files are
passed through the metadata filter (which, with no options, reads the
input and writes it back) and the output verified to match the input.

19c3df0cd6 avcodec/vc1: fix mquant calculation 
In vc1_decode_i_blocks_adv mquant needs to be reset to its default value for
each macroblock, instead of once at the beginning of the slice.

DQPROFILE specifies which macroblocks can have an alternative quantizer step
size. When DQPROFILE specifies edges, the selection is applicable to the edges
of the picture. Slice edges are not selected by DQPROFILE.
