Reading a value larger than int using atoi() may give the wrong result.

With some old libva versions <va/va.h> does not automatically include
the per-codec subsidiary headers, so we need to include the right one
explicitly ourselves.

Enables VP8 decoding - the decoder places the the bitstream version
in the profile field, which we want to ignore.

Also adds some extra fields to the main context structure that may
be needed by a hwaccel decoder.

ptrdiff_t is the correct type for array strides and similar.

It no longer serves a useful purpose.

Deprecates struct vaapi_context and the installed header vaapi.h,
to be removed at the next version bump.

Most of the functionality here has moved into lavc.

Moves much of the setup logic for VAAPI decoding into lavc; the user
now need only provide the hw_frames_ctx.

After init_opts() there needs to be an uninit_opts() call
to free the swscale context and other buffers.

This was added before edts support existed, and is no longer
valid.

This breaks files with legitimate single-entry edit lists,
and the hack, introduced in f03a081d,
has no link to any known sample in its commit message.

VP5 has no arch-specific optimizations (nor will it get some in the
future), so it makes no sense to try to share dsp init code with VP6.

This avoids SIMD-optimized functions having to sign-extend their
line size argument manually to be able to do pointer arithmetic.

Also adjust parameter names to be "linesize" everywhere.
