Also allow qmin/qmax to go up to 69 (the current max value for libx264).  This
will have to increase when we add 9/10-bit support.

Due to being pants-on-head retarded, libavcodec defaults this to zero, which
results in broken output.  This didn't affect ffmpeg.c, which sets it itself,
but caused problems for other calling apps using VBV.

Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet.

Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict
on the size of registers and which registers are being used for operations
where multiple are available. This fixes segfaults in emulated_edge()
function calls on Win64.

(cherry picked from commit 4d016dd4)

Currently (since the data_offset fix) the ogg demuxer assumes that
after the first non-header packets in any stream no more header packets
will follow.
This is not guaranteed, so change the code back again to wait until it
has finished the headers for all streams before returning from ogg_get_headers.

This fixes issue 2428.

In all 3 cases, the decoding continues and thus a warning would be sufficient.
Helps application that catch them with own log handers to handle them

This validate the length of a mkv element directly after reading
it.
This has the advantage that it is easy to add new limits and makes
it less likely to forget to add checks and also avoids issues like
bits of the length value above the first 32 being ignored because
the parsing functions only takes an int.
Previously discussed in the "mkv 0-byte integer parsing" thread.

Use avio functions instead of bytestream ones (also drops dependency on
lavc and removes a bunch of warnings).
Drop custom version of avio_get_str16 and use that instead.

In some places, dvbsubdec passes improper input buffer size to
bitstream reading functions, not accounting for reading pointer
