All the reverse-engineering work comes from AntonioND [1].
A new video backend API has been added to grab video images.
By default, a dummy backend is provided.
However, an OpenCV based backend is also provided (if enabled at
compile-time with OPENCV=1 in Makefile).
Other implementation should be possible (GStreamer for instance ?) in
the future.
With the OpenCV backend, the video device selection can be done using
the Core parameter:
[Core]
GbCameraVideoDevice=<my_device>
Where <my_device> can be either an integer which represent the device
number (0 for default) or a string which specify the video device path.
Tested with 64DD Mario Talent Studio (Japan), a transfer pak plugged
in the first controller with a Japanese GameBoy camera. Also since the
core currently requires a cart ROM (even if should strictly be required)
I used Perfect Dark (Japan) to allow using the Transfer Pak. This is a
core/ui limitation not related to this PR.

The before_install currently fails on Travis CI with:
The following packages have unmet dependencies:
libsdl2-dev : Depends: libegl1-mesa-dev
Depends: libgles2-mesa-dev
E: Unable to correct problems, you have held broken packages.
This can currently only be solved by using the apt addon to install packages.
Github provides a Travis CI integration which makes it easy to have a quick
check of a patch before a pull request is accepted. It is not enough to prove
the correctness of a contribution but at least helps to avoid some of the worst
build problems.
