    threads: change the default for threads back to 1

    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.

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.

This is consistent with the other filter descriptions.

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.

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.

That way all mix levels as exported by the parser
will have the same meaning.

Previously the 3bit center mix level for eac3 was
used to index in a 4 entry table leading to out of array reads.
this change removes the table and offsets the ac3 variable by 4
so it matches the meanings for eac3 except the reserved case.
The reserved case is then explicitly handled.

Sometimes the scan finds nothing that qualifies for addition to
the array and pos is zero after the loops.  The code forces pos to
1 and the array is then processed as if it had one valid element in it,
producing some amusing but not very useful results.

I don't see the rationale for this.  If pos is zero coming out of the
loops, the only appropriate thing to do is set t->angle to zero.  The
attached patch does that.  It's worked properly in several tests so far.

As the test is run during fate and the benchmark is useless for fate
this very slightly speeds up fate. Its also consistent with the other
tests.

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).
