Conflicts:

See: efec857cMerged-by: Michael Niedermayer <michaelni@gmx.at>

The official Ut Video decoder only threads with slices, thus until
now any files encoded by the libavcodec encoder have only been
decodable with a single thread. The default slice count is now
set to subsampled_height / 120.

Also sets slices to 1 for the Ut Video encoder tests to keep them
green.

No testcase known, this is a theoretical improvment
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Altivec can only load naturally aligned vectors. To handle possibly
unaligned data a second vector is loaded from an offset of the original
location and the data is recovered through a vector permutation.
Overreads are minimal if the offset for second load points to the last
element of data. This is 7 for loading eight 8-bit pixels and overreads
are reduced from 16 bytes to 8 bytes if the pixels are 64-bit aligned.
For unaligned pixels the overread is reduced from 23 bytes to 15 bytes
in the worst case.

There were a few grammar and spelling mistakes in this filter
description. I went through it and corrected them without changing
the meaning.
