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).

Without this, the end of the file might not be transmitted/written.

It also optionally can throttle its operation to a particular
speed, to simulate realtime writing.

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.

fixes "warning: assignment from incompatible pointer type"

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

Fixes Bug 202.

Overall almost 4% faster, idct_add down from 350 to 85 cycles, idct_dc_add
down from 83 to 30 cycles.
