  lavf: do not export av_register_{rtp,rdt}_dynamic_payload_handlers from shared objects
Merged-by: Michael Niedermayer <michaelni@gmx.at>

Note, the header was not installed so useage of this should be limited
but its not 0, there are some random pieces of code using it according
to google.

  lavc: remove old unused audio conversion functions.

Conflicts:
	libavcodec/audioconvert.c
	libavcodec/audioconvert.h

Merge only for metadata.
keeping the old API longer reduces the need for applications to be continuously
updated.

* commit '2ba68dd0':
  lavf: remove unreliable timestamp guessing heuristic

Conflicts:
	libavformat/utils.c

Not merged, as the change breaks ABI by removing a field from the middle
of AVStream.
Also, if you have files that decode better or worse without this code please
open a ticket on trac. If the timestamp code turns out useless it of course
should be removed.
