Drivers can support a format for surfaces without also supporting it for
images, so we can't assume that sw_format is usable for transfer.  This
would previously hit an assert in cases where it isn't.

decode rgtc1 block in gray8 picture

Makes the uninit function re-entrable, which can be a common case
when an API user first tries to initialize its context, fails, and
then finally unrefs the AVHWDevice.

Fixes a crash reported by sm2345 on IRC.

The commit b7c16a3f ("x86: fft: Port to
cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The
output is audible, but there's a lot of noise.

The reason for the breakage is that the commit unintentionally changed the
INTERL macro so that it is empty when compiling for 3dnow. This patch
fixes it.

device_uninit can be called twice if device_init fails.

This is helpful to know what device has actually been used.

Both are autodetected, and their dependency on cuda is checked
elsewhere.

This was added for compatibility with libav, by leaving a space for
formats added in libav to be merged.  Since that feature has been
removed, we don't need a gap here.

nvdec will not produce odd width/height output, and while this is
basically never an issue with most codecs, due to internal alignment
requirements, you can get odd sized jpegs.

If an odd-sized jpeg is encountered, nvdec will actually round down
internally and produce output that is slightly smaller. This isn't
the end of the world, as long as you know the output size doesn't
match the original image resolution.

However, with an hwaccel, we don't know. The decoder controls
the reported output size and the hwaccel cannot change it. I was
able to trigger an error in mpv where it tries to copy the output
surface as part of rendering and triggers a cuda error because
cuda knows the output frame is smaller than expected.

To fix this, we can round up the configured width/height passed
to nvdec so that the frames are always at least as large as the
decoder's reported size, and data can be copied out safely.

In this particular jpeg case, you end up with a blank (green) line
at the bottom due to nvdec refusing to decode the last line, but
the behaviour matches cuviddec, so it's as good as you're going to
get.
