  h264: increase MAX_SLICES to 32

The available sample decodes correctly before, but the reporter of the bug
claims that this change reduces artifacts. This is thus merged
If someone has samples that decode differently depending in the MAX_SLICES
value, please open a ticket on trac.
Also this change should be reverted if it turns out that the artifacts
that where seen had a different cause

The Extensible Metadata Platform tag can contain various kind of data
which are not strictly related to the video file, such as history of edits
and saves from the project file. So display XMP metadata only when the
user explicitly requires it.

Based on a patch by Marek Fort <marek.fort@chyronhego.com>.

These tags describe the product and quicktime library version respectively.
They originate from Adobe Premiere, but also some other programs use them.
Contrary to other tags, they contain 'raw' data which is not to be
interpreted as iso639 or mac strings.

Based on a patch by Peter Ross <pross@xvid.org>.

Alphabetically order the list by the tag to facilitate the insertion of
new ones.

H264 streams from CounterPath Bria and some Cisco phones need an
increased pool for correct decoding.

This uses the RIFF header stored size to figure out the expected AVI
file size, instead of the actual file. To work fully it requires handling
failed avio_seek() instead of assuming they always succeed.

Some fate file has been cut off and contains half a frame at the end which
previously was not output during demuxing. This frame is now output to
encoder, thus the fate diff update.

According to the DPX file format description found at
http://www.fileformat.info/format/dpx/egff.htm the ImageElement part of
the GenericImageHeader also contains an an offset to the real image data
beside the same member that can be found in the GenericFileHeader.

Libav keeps this member empty (=0) while some applications expects it to
be filled properly. FATE test updated accordingly.
