Any other x265 symbol may not exported, e.g. if the build is a
multilib (10-bit and 8-bit in one) build.

This is the only symbol we directly call, and is available in the
build number we check for.

Fixes the configure check on multilib x265 builds.

This HWAccel isn't really usable right now due to an nvidia driver bug,
so we don't want it selected by default.

HWAccels have a capabilities field and there's a comment about flags,
but no flags exist today, so let's add one for experimental hwaccels.

The intention of this change is to allow separation of API tests from the
existing tests, and also to have a place for the API test source/executable
files so they're not mixed in with the actual library code.

  vc1dec: use get_bits_long and limit the read bits to 32

See: 1f1e0a29Merged-by: Michael Niedermayer <michaelni@gmx.at>

If nb_samples is zero, the bit_rate calculation results in a division by
zero.

Since ff_get_buffer fails if frame->nb_samples is zero, this can be
fixed by moving the bit_rate calculation after that function call.

That also makes it possible to reuse the already calculated
frame->nb_samples value.

This change introduces basic support for HEVC decoding through vdpau.
Right now, there are problems with the nvidia driver/library implementation
that mean that frames are incorrectly laid out in memory when they are
returned from the decoder, and it is normally impossible to recover the
complete decoded frame due to loss of data from alignment inconsistencies.

I obviously hope that nvidia will be fixing it in due course - I've verified
the problems exist with their example application.

As such, this support is not useful for any real world application, but I
believe that it is correct (with the caveat that the mangled frames may hide
problems) and will work properly once the nvidia problem is fixed.

Right now it appears that any file encoded by x265 or nvenc is decoded
correctly, but that's because these files don't use a bunch of HEVC
features.

Quick summary:

Features that seem to work:

1) Short Term References
2) Scaling Lists
3) Tiling

Features with known problems:

1) Long Term References

It's hard to tell what's going on here. After I read the nvidia example
app that does not set the IsLongTerm flag on LTRs, and changed my code,
a bunch of frames using LTR started to display correctly, but there
are still samples with glitches that are related to LTRs.

In terms of real world files, both x265 and nvenc only use short term
refs from this list. The divx encoder seems similar.
