The logic for enabling gstreamer support in opencv is not correct. We
select gstreamer-0.10 packages but then we enable gstreamer1 support in
the opencv.mk file. opencv3 has the correct logic, so let's use it in
opencv as well.

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.

Since there is a couple of API breaks between OpenCV 2.4 and 3.0, two
distinct packages mutually exclusive will be integrated in the package
tree.
So, this change prepares the re-introduction of the OpenCV-2.4 package
by renaming the current opencv package (which provides OpenCV-3.0) to
opencv3.
Reverse dependencies (vlc) is fixed to use the new symbols.

In OpenCV, OpenGL is only used by highgui module.
OpenGL support is done using extensions from 3rd party framework: either
Qt5OpenGL with Qt5 (with GL support only, not GLES); or gtkglext (which
is not available in Buildroot) with gtk2
So, make OpenGL knob a sub-option of the Qt5 support option.
Note: we enclose both the GUI toolkit choice and the GL option in an
if-block, so that the GL option gets properly indented; having it
depend on WITH_QT5 is not enough, because it does not directly follow
it, so kconfig would not consider it for indenting.

Starting with the 2.4.6 release, OpenCV supports either Qt4 or Qt5 as GUI
toolkit, so add Qt5 in the GUI toolkit choice.
When Qt4 is enabled (and thus Qt5 is hidden and disabled), no need to
show a comment stating "Qt5 support needs Qt5", because Qt5 is not
selectable.
Conversely, when Qt5 is enabled and Qt4 is not, then no need to show a
comment stating "Qt4 support needs Qt4", because enabling Qt4 would
disable Qt5.
So, we only show the comments when neither toolkit is enabled.

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.

Starting with the 2.4.7 release, for V4L support, OpenCV does not
requires a libv4l dependency for its V4L support.
So, it now provides 2 distincts knobs for this: WITH_V4L and a new
one: WITH_LIBV4L.
This patch takes advantage of this new knob and libv4l support is
now automatically enabled only if the libv4l package is enabled.
In OpenCV, the logic behind this is:
- using libv4l if available,
- otherwise, use v4l2 or v4l API from the kernel if available.

This patch bumps OpenCV version and address the minimal set of change to
get the new version building correctly:
- update the download location;
- force Qt version to Qt 4 when support is enabled;
- naively fix the v4l support.
However, it does not address a couple improvements, among these:
- jasper support;
- python/numpy support;
- Qt4 and Qt5 support (since the 2.4.6 release), so only Qt4 support is
supported in this patch;
- optional libv4l dependency (since 2.4.7 release);
- etc.
These will be addressed in followup patches.

It does not make much sense enabling opencv without its core module.
This configuration leads to build nothing (since all modules depend on
the core one), but install the configuration files (*.pc and *.cmake)
anyway.
This absurd situation may break the build-system of other packages
that would correctly find the *.pc (but does not check for the modules
they actually use), but would not build because of missing headers and
libraries.

The opencv package selects zlib, but it does not depend on it. This
leads to cases where opencv gets built before zlib, and in this case,
opencv uses its internal version of zlib, which doesn't build properly
