Actual allocation size is computed as (count + 1)*sizeof(meta_keys), so
we need to check that (count + 1) won't cause overflow.

nvenc still encodes as yuv, but does the conversion internally which
brings some performance gains.

Fixes regressions with stream copy and output timebase/fps being twice as fine as needed
Makes the timebase and ticks per frame handled identical which should make the
code easier to understand and work with. It does not solve the problem without
st->codec access

Previously, we used a different list of checks when deciding whether to
write a set of tags at all than we did when deciding whether to write an
individual tag in the set. This resulted in sometimes writing an empty
tag master and seekhead. Now we use mkv_check_tag_name everywhere, so
if a dictionary is entirely composed of tags we skip, we don't write a
tag master at all.
This affected the test file, since "language" was on one list but not
the other, so we were writing an empty tag master there. The test hash
is updated to reflect that change.
Right now, if we attempt to use cuvid in a media player and then
try to seek, the decoder will happily pass out whatever frames were
already in flight before the seek.
There is both the output queue in our code and some number of frames
within the cuvid decoder that need to be accounted for.
cuvid doesn't support flush, so our only choice is to do a brute-force
re-creation of the decoder, which also implies re-creating the parser,
but this is fine.
The only subtlty is that there is sanity check code in decoder
initialisation that wants to make sure the HWContextFrame hasn't already
been initialised. This is a fair check to do at the beginning but not
after a flush, so it has to be made conditional.

cuvid/nvdecode also supports mpeg1, mpeg2, h.263/mpeg4-asp and mjpeg.
It should, in theory, also support wmv3 via the vc1 support, given
that vdpau supports this. However, it failed to play wmv3 samples
which vdpau played correctly, so I'm not sure what to make of it.

This patch is a fix for the bug with ticket number 5812
(https://trac.ffmpeg.org/ticket/5812).
Basically, the bug is that the last segment and the "#EXT-X-ENDLIST"
tag are not being written to the subtitle playlist file when
converting a file with subtitles to the HLS format. The reason for
this seem to be that the filename for the subtitle file is being freed
too early. This solution is simply to free that memory after it's last
use in the "hls_window" function.
