sdp: Add an option for sending RTCP packets to the source of the last packets

An SDP description normally only contains the target IP address
and port for the packets. This means that we don't really have
any clue where to send the RTCP RR packets - previously they're
sent to the destination IP written in the SDP (at the same port),
which rarely is the actual peer. And if the source for the packets
is on a different port than the destination, it's never correct.

With a new option, we can choose to send the packets to the
address that the latest packet on each socket arrived from.
---
Some may even argue that this should be the default - perhaps,
but I'd rather keep it optional at first. Additionally, I'm not
sure if sending RTCP RR directly back to the source is
desireable for e.g. multicast.

Signed-off-by: Anton Khirnov <anton@khirnov.net>

Make new VDPAU easier to use by adding context to callback.

Using VDPAU correctly means checking for preemption
and possibly regenerating the context all the time.
With the current API there is no context or other
user-defined pointer and thus this in not possible
during decoding unless using some hack like global
variables.
The need to reinitialize both surfaces and even function
pointers makes handling preemption even more difficult.
This patch introduces a new render2 function that gets
both the AVCodecContext and AVFrame in addition,
in both the user can store additional opaque data.
This allows even advanced approaches like keeping a
"generation counter" for the surfaces so they can be
regenerated on the fly and efficiently.
In addition, the function has a return value that will
be passed through all the way instead of being silently
ignored as for the current render function.
Unfortunately the HWAccel API has no way of providing
API/ABI compatibility, so a currently disallowed
state (render pointer being NULL) is used to extend it.

avformat/id3v2enc: use UTF-16 in id3v2.3 APIC frame only if non-ASCII

This makes the encoding of picture descriptions consistent with the
encoding of other text id3 tags and works better with iTunes, which
does not display pictures with some UTF-16 picture descriptions
(including a UTF-16 empty string, i.e. BOM + terminator).  It also
saves a few bytes.

Example:
 ffmpeg -f lavfi -i sine=b=4 -f lavfi -i smptebars -map 0:a -map 1:v \
   -codec:a libmp3lame -codec:v mjpeg -id3v2_version 3 \
   -metadata:s:v comment="Cover (front)" -t 3 -y out.mp3

This example does not set a picture description (-metadata:s:v title=)
so an empty string is written in the id3v2.3 APIC frame.  Without this
patch, UTF-16 is used and the cover art does not display in iTunes.
With the patch the cover art is displayed.  (Note that iTunes does not
display or have a way to set picture descriptions, only the picture
itself, but nevertheless has trouble skipping some UTF-16 descriptions.)
