libvpx can be compiled with the VP8 decoder and encoder disabled, and
there's no reason to force their presence if the user only wants VP9.

The entry for file protocol option 'follow' was inserted under ftp options
during merge of a Libav commit - 90eb2499. Corrected.

autorotate is enabled by default in ffmpeg so the rotation filters
are required and will be attempted for insertion without the user's
knowledge if an input stream has rotation side-data.

Testcases which return 403 currently are commented out

After this change we always parse the full specifier even if we know the result
in the middle of the parsing. Sligtly slower, but this is needed to
consistently reject incorrect specifiers in both matching and non-matching
cases.
Signed-off-by: Marton Balint <cus@passwd.hu>

This reworks the code to be more strict about accepting stream specifiers. From
now on we strictly enforce the syntax in the documentation up until the
decisive part of the stream specifier. Therefore matching stream specifiers
always need to be correct, non matching specifiers only need to be correct
until the decisive part.

Also recursion is changed to a simple loop.

This improves compatibility with some consumer (LG WebOS) TVs which apparently
search a HEVC descriptor (which our mpegts muxer can't generate) or a format
identifier.

Since the HEVC format identifier is not registered (but used in the wild), it is
not written if strict_std_compliance is higher than normal.

This fixes the issue in ticket #7744.

With all of our existing users of cuda_sdk switched over to ffnvcodec,
we could remove cuda_sdk completely and say that we should no longer
add code that requires the full sdk, and rather insist that such code
only use ffnvcodec.

As discussed previously, the use of nvcc from the sdk is still
supported with a distinct option.

This change switches the vf_thumbnail_cuda filter from using the
full cuda sdk to using the ffnvcodec headers and loader.

Most of the change is a direct mapping, but I also switched from
using texture references to using texture objects. This is supposed
to be the preferred way of using textures, and the texture object API
is the one I added to ffnvcodec.
