fb59f87ce7 nvenc: Explicitly push the cuda context on encoding
Make sure that NVENC does not misbehave if other cuda usages happen
in the application.

6f58b4dc47 nvenc: drop the hard dependency on CUDA
The code needs only a few definitions from cuda.h, so define them
directly when CUDA is not enabled. CUDA is still required for accepting
HW frames as input.

Based on the code by Timo Rothenpieler <timo@rothenpieler.org>.

118beda355 nvenc: merge input and output surface structs
An input frame always corresponds to exactly one output packet, so there
is no point in complicating the situation by managing them separately.

c59fec783d nvenc: generate dts properly
When there is a non-zero decoding delay due to reordering, the first dts
should be lower than the first pts (since the first packet fed to the
decoder does not produce any output).

Use the same scheme used in mpegvideo_enc (which comes from x264
originally) -- wait for first two timestamps and extrapolate linearly to
the past to produce the first dts value.
