1d642ebfdb avformat/hls: don't propagate deprecated "user-agent" AVOption 
This code will print a warning if any user agent is set - even if the
API user used the proper non-deprecated "user_agent" option.

This change should not even break anything, because even if the user
sets the deprecated "user-agent" option, http.c copies it to the
"user_agent" option anyway.

022d4a2114 avformat/matroskaenc: do not write timebase as framerate 
If the API user doesn't set avg_frame_rate, matroskaenc will write the
current timebase as "default duration" for the video track. This makes
no sense, because the "default duration" implies the framerate of the
video. Since the timebase is forced to 1/1000, this will make the
resulting file claim 1000fps.

Drop it and don't write the element. It's optional, so it's better not
to write it if the framerate is unknown.

Strangely does not require FATE changes.

bad42e9b40 lavf/dashenc: pass standards compliance value to the internal context 
Enables one to test possibly nonstandard formats such as Opus or
FLAC in ISOBMFF, among other things.

This becomes much more useful if output segment format becomes an
option, or if the WebM segment feature gets removed.

fragments.
