allcodecs: move libaacplus down.

We choose the first encoder by default and libaccplus has a
quite limited set of supported bitrates/sample rates.
Thus leading to failure by default in many cases when it is
enabled at compile time.
Moving it down means that the other aac encoders are favored

mxfdec: Fix regression on files from Pinnacle Thunder

The reason for this is that such files have IndexTableSegments which when parsed
cover EditUnit ranges like this:

 [0,1)
 [249,250)
 [249,377)
 [0,249)

where each interval is [IndexStartPosition,IndexStartPosition+IndexDuration).
This would be reduced to a sparse index like:

 [0,1), [249,250)

instead of the full range:

 [0,249), [249,377)

repeat until convergence:

    force this format on all output links of the same type (if possible)

MOV: Fix old-style muxed raw-audio data.

This patch fixes the sample from trac issue #522.
The issue is that the mov demuxer insists on using its
calculated sample_size (which is nonsense for old-style tracks)
instead of the one encoded in the track.
The old raw audio code should be using the value in stsz, because
the size of a single sample never makes sense for the size of
a full audio packet, whereas the new code will multiply the
sample size by the chunk size, so it should use the calculated value.

a start of a page, thus some keyframes still would not
get their own granule.
The real problem is that header packets must not be flushed,

be detected as keyframes.
