package/opencv: bump to version 3.0

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.
