The dependency is indirect through the h263/mpegvideo code.

We cannot easily determine if an mpeg TS's packet size is DVHS, FEC
or so on, for that we need to expose the internal raw_packet_size
field.

It was never used since it was added and the things it was intended for
are now exported differently.

The section name is the muxer, not the format.

Keep the sections alphabetically sorted.

Also add warning comment about threading implementations without matching
atomics implementation to the atomics fallback implementation.

Previously the default fragmentation method was only enabled
if writing an ISM file.

If linking in an object file without this attribute set, the
linker will assume that an executable stack might be needed.

@parblock is only supported in very recent Doxygen versions.

Also drop support for building examples in library directories.

'11b' is reserved in the A/52 specification,
but newer encoders use it to indicate a Dolby
Pro Logic II compatible Lt/Rt downmix.

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.

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.

Add properly formatted @example tag and fix Doxygen syntax.

This allows using the libav source path as the example path.

These files are referenced elsewhere and only generate warnings if
presented to Doxygen as input files.
