Make midstream AVStream.codecpar updates optional and disabled

Is this signaled in any way or is the client expected to check if
codecpar has changed?
The client is expected to check codecpar for changes ...
What performance impact does this have ?
In my player? None that I cared to measure
MPEG-TS and MPEG-PS can have a new PMT (TS) or PSM (PS) at any time to
do any of the following: modifying current streams, adding new streams,
or removing streams. Therefore, to fully support those containers, you
need to check if the version numbers have changed anyways (or be
notified by a callback).
libavformat/mpeg.c does not use the program_stream_map_version.
