The s->ssrc field is the sender's SSRC, we use ssrc + 1 to get
a collision free "unique" SSRC for ourselves in the RR part.
The SDES block in the RTCP packet should describe ourselves,
not the sender.

This was fixed for the RR part in 952139a3, but wasn't
fixed for the SDES part until now.

This could cause some Axis cameras to send RTCP BYE packets
to us due to the SSRC collision.

Using threaded decoding by default breaks backward compatibility if
AVHWAccel is used or if an appliction sets threadunsafe callbacks.
Avconv and avplay still use -threads auto if not specified.

They are used to signal the number of slices and offsets of each slice
out of band to the decoder.

Also include stdlib.h explicitly - currently it is used
implicitly via avformat.h.

This temporarily (until 0.8 is released) reverts commit
8e1340ab. That commit breaks shared
builds because of symbol hiding. Reverting it will enable shared builds
for 0.8

When either video dimension is only one macroblock, subtractions
based on v_edge_pos and the macroblock size may be negative. In
that situation, an unsigned comparison isn't sufficent to test for
MV overruns, because a limit of (unsigned)-1 will let any other
value pass.

Originally, sizeof(struct MOVIentry) was 48, after the reordering,
it is 40 in my build configuration.

When writing really long mov/mp4 files, this can make a difference
- this saves a bit over 2 MB of memory per hour of video (down to
10.3 MB per hour from 12.3 MB per hour initially) for a video with
75 packets per second - 25 fps + 50 audio packets (which is the
case for AMR audio).

The H.264 decoder needs SPS and PPS for initialization during
multi-threaded decoding. When probed single-threaded SPS and PPS are
copied to extradata and are available for proper initialization of
the decoder before the first frame is decoded.

Frames must be counted when they are passed to the encoder, not when
they come out.

Fixes Bug 202.
