The filter needs input frames with color properties filled out by
the decoder. Since this is not always possible, add input options to
the filter so that user may override color space, color primaries,
transfer characteristics, and color range, as well as a generic option
to set all properties at once.

Fixes ticket #5786.

DQT segments may contain 0xFFs which break auto-detection.

They may contain 0xFFs, confusing the start code finding algorithm.

Fixes ticket #5819.

For some reason, when compiling with gcc-asan and a recent enough gcc
version(seen on 5.3+ so far), linking dlopen works without -ldl, but
dlsym fails with:

undefined reference to symbol 'dlsym@@GLIBC_2.2.5'

So this patchs checks for both dlopen and dlsym to work for determining
if -ldl is needed.

Including this header in a C++11 program (inside extern "C") will
throw an error because it looks like a user-defined literal.  Add a
space between the two tokens to avoid the problem.

Commit 2b1d316f made nvenc depend on
LoadLibrary, but the availability of the latter was never checked.

This fixes nvenc on Windows platforms

Sometimes it's useful to be able to define the exact track numbers in
the generated track, instead of always beginning at track id 1. Using
the option use_stream_ids_as_track_ids now copies the use stream ids
to track ids. Dynamically generated tracks (ie. tmcd) have their track
numbers defined as continuing from the highest numbered stream id.
