* commit '596e5d4783ca951258a7c580951fd161f1785ec1':
  lavf: Add a flag to enable/disable per-packet flushing

Conflicts:
	libavformat/avformat.h
	libavformat/mux.c
	libavformat/version.h

This adds a 2nd API to set per packet flushing
If the user application indicates through either a non default then this non default takes
precedence over the other still default value
