As Jonathan noticed in [1], users' applications may depend on opencv-2.4
APIs removed in opencv-3.0.
So, re-introduce opencv package as it was right before the bump to
opencv-3.0 (i.e.: commit bf00b5a9ea).
We do not support both OpenCV-2.4 and OpenCV-3 at the same time, so make
OpenCV-3 depend on !OpenCV-2.4.

[yann.morin.1998@free.fr:
- remove legacy symbols, now
- make opencv3 depends on !opencv, not the other way around
- slitghly reword the commit log (opencv/opencv3 dependency)

This major version bump is in fact a bump from 2.4.10 to 2.4.11, then to
3.0.
OpenCV-2.4.11 improves a lot the Buildroot integration, including a
couple of patches that are no longer needed:
- x86 PIC code compilation fix in core module [1];
- return type fix in superes module [2];
- opencv.pc generation [3].
It also improves the gstreamer-0.10/1.x detection [4], that will be
needed in a follow-up patch.
OpenCV-3.0 still requires 2 patches (backported from upstream fixing
pthread support [5,6].
The OpenCV-3.0 does some major changes, for which a transition guide
has been published [7].
Among these changes coming with OpenCV-3.0, some new modules have been
introduced and others got removed; leading to a bunch of configure
option updates (to keep as much as possible an iso-functional-perimeter)
and the legacy menu has been updated too.
The worth noticing removals being:
- the opencv_legacy and opencv_nonfree modules no longer exist;
- the opencv_contrib module has moved out of the opencv base tree and
now has its own repository [8].
There is currently no plan to support it.
Some 3rd-party supports have been improved or added; their integrations
in Buildroot will be addressed in follow-up patches.
