c75922b96b basevideodecoder: fix weird event list handling 
Get rid of weird code that copies a list manually, taking
ownership of the elements and then frees the old list. Instead,
just take over the old list entirely. (If the intent was to
reverse the list, one could use g_list_reverse() instead).

Then, push events in the list out from last to first (since they
were prepended as they came in) instead of just pushing out the
last in the list and leaking the others.

context could be X11 Display, VaDisplay, etc.

8a044de701 basevideoenc: do not try to calculate latency from an unknown framerate 
It'll divide by zero, and latency is unknown for an unknown framerate.

Fixes an assert in the schroenc test.

d576e23aa4 basevideoencoder: Proxy the width/height/framerate/PAR constraints of downstream caps to upstream 
This allows to specify constraints on the compressed downstream caps
by muxers or capsfilters, which will then be forwarded to upstream
and allows video converters to fulfill the constraints.

Code based on Mark Nauwelaerts audio encoder base class.

4a76d3a978 basevideoencoder: Remove ::get_caps() vfunc 
Subclasses can set the caps more efficiently and this only
caused additional indirections.

2dbd24ca84 basevideoencoder: Use a temporary GstVideoState until the subclass accepted the caps 
Also store the caps in the GstVideoState and assume a PAR of 1/1 instead
of 0/1 if no PAR is specified in the caps.

on a different thread than the sinkpad streaming thread.

f341386b64 basevideodecoder: Don't reorder serialized src events 
And allow to drop EOS by the subclass if ::finish returns
DROPPED. This requires that the subclass sends EOS manually later.

525875727a basevideo: Add the caps to the GstVideoState and clean up caps/codec_data properly

non-standard caps fields like the h264 alignment must be accessed.
