libav: Update AVCodecContext lifetime to work properly with ffmpeg 7
...
avcodec_close() is deprecated and it's not supported anymore to re-open
a codec, so we only ever allocate the codec in set_format() now and
always free it after usage.
As part of this, also fix various memory leaks in related code paths.

avvidenc: Don't take ffmpeg timestamps verbatim but only use them to calculate DTS
...
The ffmpeg timestamps are inaccurate and only in framerate granularity.
To avoid generating inaccurate output timestamps, especially with
variable framerate streams, only use the ffmpeg timestamps for
calculating the DTS.

Otherwise ffmpeg's rate control algorithm will not work correctly as

avvidenc: Set timebase in the ffmpeg context to nanoseconds and set framerate
...
As we now actually use the timestamps from ffmpeg for timestamping the
output we would lose a lot of accuracy if the framerate is used.

gst-libav: fix build with ffmpeg-5.0.0
...
Latest ffmpeg has removed avcodec_get_context_defaults(), and its
documentation says a new AVCodecContext should be allocated for this
purpose. The pointer returned by avcodec_find_decoder() is now
const-qualified so we also need to adjust for it. And, AVCOL_RANGE_MPEG
is now rejected with strict_std_compliance > FF_COMPLIANCE_UNOFFICIAL.
