FooterPartition offset specified in RIP takes precedence over any value written
in PartitionPacks. This fixes the same issue f06f6da tries to fix without
introducing an extra variable.

Without this patch the demuxer can get stuck in a loop if PreviousPartition
points somewhere where there's no PartitionPack, or if klv_read_packet() syncs
back up to the current partition.
This should fix Ticket3278 properly and unbreak Ticket4040.

This check is redundant with the previous commit but it provides
better error messages and feedback while the previous commit
ensures that var_read_string() doesnt return uninitialized arrays
if it itself is feeded with an invalid size possibly through a
different future codepath.

vdpau: return MAIN instead of BASELINE for H.264 CBP

* commit '26ab504ad8d2b23535c9a0ad43bf1fd0e6aa0893':
vdpau/h264: request MAIN rather than BASELINE VDPAU profile for CBP
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The H.264 Constrained Baseline Profile (CBP) is a subset of both the
Main Profile and the Baseline Profile. In principles, a hardware
decoder that supports either of those can decode CBP content. As it
happens, Main is supported by all VDPAU drivers, and Baseline is not.
So favor map CBP to MP for now. Hopefully in the future libvdpau will
offer an explicit choice for CBP.
This fixes bug 757.

should be the raw amount of pixels (for example 3840x1080 for full HD side by
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
one plane (1920x1080 for that full HD stream)."
So, move the aspect ratio check in the mkv_write_stereo_mode() function
and always write the embl when stereo format and/or aspect ration is set.
Also add a few comments to that function.

The coefficients must be in the appropriate zigzag scan order.
Also fix their values at the same time, as they were pretty wrong.
