7fbc082577 compat/cuda/ptx2c: strip CR from each line
Windows nvcc + cl.exe produce a .ctx file with CR+LF newlines which
need to be stripped to work with gcc.

17f63d98e6 compat/cuda: update cuvid/nvdec headers to Video Codec SDK 8.0.14
This raises the required minimum NVIDIA display driver versions:
NVIDIA Linux display driver 378.13 or newer
NVIDIA Windows display driver 378.66 or newer

81147b5596 avcodec/cuvid: Add support for P010/P016 as an output surface format
The nvidia 375.xx driver introduces support for P016 output surfaces,
for 10bit and 12bit HEVC content (it's also the first driver to support
hardware decoding of 12bit content).

The cuvid api, as far as I can tell, only declares one output format
that they appear to refer to as P016 in the driver strings. Of course,
10bit content in P016 is identical to P010, and it is useful for
compatibility purposes to declare the format to be P010 to work with
other components that only know how to consume P010 (and to avoid
triggering swscale conversions that are lossy when they shouldn't be).

For simplicity, this change does not maintain the previous ability
to output dithered NV12 for 10/12 bit input video - the user will need
to update their driver to decode such videos.

843aff3cf7 cuvid: Use bundled headers
We need to remove the dynlink fanciness and replace it with normal
function prototypes and update the include paths and configure logic.

We don't need to explicitly check for PICPARMS now - they're going
to be there.

f59e10b0f4 cuvid: Add MIT licenced nvcuid headers from Video SDK 7.0
For unknown reasons, the only accurately descriptive version of
cuviddec.h is in the Video SDK - the one in CUDA 7.5 lacks vp8
PICPARAMS and the vp9 struct definition is inaccurate. The CUDA 8 RC
includes an ancient version of this file from many many years go.

However, the one in the Video SDK is modified to work through a
dynamic link mechanism which we don't really want to use, so the
next change will modify the files to just declare functions in
the normal way.

I've split the changes so it's clear to see what changed between
the original files and ones that work for us.
