0940580adb lavc: Correct the description of pkt_dts 
The description as updated in 6e5c44b0f made it sound like it is
handled exactly like the pts, which it is not. Clarify that it
is the packet that triggered returning the frame instead of just
the last avpacket (in case of frame threading, it won't be the
dts of the last packet).

8e134e5104 lavc: clarify get_buffer() documentation 
This is needed for the AAC decoder, which may need to call get_buffer()
more than once if the channel configuration changes.

9b500b8f6c avcodec: Add a RFC 3389 comfort noise codec 
This isn't too useful as a normal codec, but can be used in
voip style applications. The decoder updates the noise
generator parameters when a packet is given to it for decoding,
but if called with an empty packet, it generates more noise
according to the last parameters.

2ff67c909c lavc: fix mixing CODEC_ID/AV_CODEC_ID in C++ code. 
C++ does not allow to mix different enums, so e.g. code comparing
ACodecID with CodecID would fail to compile with gcc.

This very evil hack should fix this problem.

avcodec_find_best_pix_fmt2() uses a PIX_FMT_NONE terminated list
