OpenCV's highgui module needs to be auto-selected when the ts module is
selected, because it depends on it. Otherwise it would fail with an

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.

Only the highgui module can use Qt or GTK (as noticed by Thomas.)
However, it is currently possible to select the Qt or the GTK backends
support independently of highgui, thus breaking the configuration step
of opencv.
Just hide the Qt and GTK backends when highgui is not selected.

The core module of OpenCV is now using the pthread_spin_*() API, which
is only available in the 'linuxthreads' and 'NPTL' thread
implementations, but not in the 'linuxthreads.old'
implementation. Therefore, this commit adds a dependency on OpenCV to
NPTL threads.

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.

The OpenCV highgui module links against QtGui and QtTest.
The latter is built by default but was never installed.
Thanks to the previous patch on Qt, this can be rectified.

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
(it has some conditional code for ARM that is probably broken), see:
http://autobuild.buildroot.org/results/45f4e195fe0cc5acace10287f5ff33aa953d5430/build-end.log
We fix this by properly adding the opencv dependency on zlib.
