[Buildroot] [git commit] package/opencv: bump to version 3.0

commit: http://git.buildroot.net/buildroot/commit/?id=a9043951b93d206363fd8fda6863fc0259b90858
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.

-
-This is caused because the return value of the createFrameSource_Video_GPU function should be a VideoFrameSource_GPU object.

-Subject: [PATCH] cmake/OpenCVGenPkgconfig.cmake: rework opencv.pc generation
-
-Using absolute path to locate the components in the "Libs:" field of the
-*.pc can badly break cross-compilation, especially when building
-statically linked objects.
-
-Indeed, pkg-config automatically replaces the '-I...' and '-L...' paths
-when the PKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_LIBDIR environment
-variables are set [1]. This feature is very helpful and common in
-cross-compilation framework like Buildroot [2,3].
-
-When there are absolute paths in the *.pc files, pkg-config won't be
-able to do the path substitions for these paths when the afromentioned
-environment variables are set.
-In such case, since the prefix is the target one, not the sysroot one,
-these libraries' abolute paths will point to:
-- in the best case: a non-existing file (i.e. these files do not exists
-  on the host system;
-- at worst: the host system's libraries. This will make the linking
-  failed because these host system's libraries will most likely not be
-  build for the target architecture [4].
-
-So, this patch replace the components' absolute paths by the form:
-  -L<libdir> -l<libname>
-
-This way, the linker will be able to resolve each dependency path,
-whatever the kind of objects/build (shared object or static build) it
-is dealing with.
-
-Note that for static link, the library order does matter [5]. The order
-of the opencv components has been carefully chosen to comply with this
-requirement.
-
-Fixes #3931
