Add code to reinitialize all VDPAU objects if a display preemption
condition occurs. Reinitializing them in the middle of playback will
cause video corruption at least until the next keyframe when using
hardware decoding, but decoding does seem to recover after a keyframe.
Create a single large bitmap surface for EOSD objects and pack all the
bitmap rectangles inside that. The old code created a separate bitmap
surface for every bitmap and then resized the cached surfaces when
drawing later frames. The number of surfaces could be large (at least
about 2000 for one sample subtitle script) so this was very
inefficient. The old code also used a very simple strategy for pairing
existing surfaces to new bitmaps; it could resize tiny surfaces to
hold large glyphs while using existing large surfaces to hold tiny
glyphs and as a result allocate arbitrarily much more total surface
area than was necessary.
The new code only supports using a single surface, freeing it and
allocating a larger one if necessary. It would be possible to support
multiple surfaces in case of hitting the maximum bitmap surface size,
but I'll wait to see if that is actually needed before implementing
it. NVIDIA seems to support bitmap surface sizes up to 8192x8192, so
it would take either a really pathological subtitle script rendered at
a high resolution or an implementation with lower limits before
multiple surfaces would be necessary.
The packing algorithm should successfully pack the bitmaps into a
surface of size w*h as long as the total area of the bitmaps does not
exceed 16/17 (w-max_bitmap_width)*(h-max_bitmap_height), so there
should be no totally catastrophic failure cases. The 16/17 factor
comes from approximate sorting used in the algorithm. On average
performance should be better than this minimum guaranteed level.
Add a template file that contains a single listing of various
information needed about the VDPAU interface functions, and is then
included multiple times to create required declarations and tables.
Previously some of the information needed to be duplicated for each of
those uses.
this version of the check assumes that we run on a system with apt-get
installed and configured. We should probably check that this is actually
true. Or more ideally add support for yum for fedora systems.

We were using an inconsistent mix of the three variants and 'volatile' should
be the most correct and portable variant.

Neither variant is valid C99 syntax, but __asm__ is the most portable variant.

This is what it is called in FFmpeg and more consistent with other
names for similar conditionals. This fixes a potential compilation
failure on MinGW, as described in Bugzilla #1262.
