This commit handles the reverse dependency tree of cairo in terms of
atomic dependencies. There are two main changes:
- cairo in fact no longer needs atomic operations. It can perfectly
build without any __sync built-in, as was tested using an ARC
toolchain without atomics, and a SPARC toolchain. Optionally, Cairo
can use the __atomic builtins provided by gcc >= 4.7, so support
for this is added as well. Thanks to this change, the
BR2_ARCH_HAS_ATOMICS dependency is removed from cairo and all its
reverse dependencies.
- harfbuzz does require the __sync built-in for 4 bytes integers, so
we add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 to harfbuzz and all
its reverse dependency, the main one being the pango package. Due
to this, the vast majority of gtk-related packages are moved to a
dependency on BR2_ARCH_HAS_ATOMICS (which used to be due to cairo)
to a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 (due to pango ->
harfbuzz).
In detail:
- cairo
Remove BR2_ARCH_HAS_ATOMICS dependency, link against -latomic when
gcc >= 4.8 in order to use the __atomic functions.
- harfbuzz
Add dependency on BR2_TOOLCHAIN_HAS_SYNC_4
- cairomm, gst-plugins-good, gst1-plugins-good, libgdiplus,
libsvg-cairo, weston
Remove BR2_ARCH_HAS_ATOMICS dependency (since cairo no longer needs
atomics)
- enlightenment, cwiid, gst-plugins-bad, gst-plugins-base,
gst1-plugins-bad, gst1-plugins-base, gtkmm3,
libevas-generic-loaders, libfm, libgail, libgtk2, libgtk3, librsvg,
openbox, opencv, opencv3, pango, pangomm, pcmanfm, pinentry,
rrdtool, webkit, webkitgtk24, xscreensaver
Switch from a BR2_ARCH_HAS_ATOMICS dependency to a
BR2_TOOLCHAIN_HAS_SYNC_4 (they depend on pango, harfbuzz, gtk, or
some other related package)
- directfb
Remove BR2_ARCH_ATOMICS dependency of the BR2_PACKAGE_DIRECTFB_SVG
(since cairo can build without atomics), but add a
BR2_TOOLCHAIN_HAS_SYNC_4 dependency on BR2_PACKAGE_DIRECTFB itself
since it does use __sync built-ins. This replaces the !BR2_sparc
dependency.

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.

ffmpeg was already marked as not available for the NIOS2 Sourcery
toolchains, but it could still be built with the internal toolchain
backend or a custom external toolchain.
However, an inspection of the latest glibc source code indicates that
FE_INVALID, FE_OVERFLOW and FE_UNDERFLOW and indeed not available in
the nios2 variant of <fenv.h>.
Consequently, this patch makes ffmpeg not available on nios2, which
allows to simplify a bit the dependencies.
It propagates this dependency to:
- minidlna (and at the same time makes sure the minidlna comment is
not displayed on nios2, which wasn't properly taken into account
until now)
- mpd
- opencv
- opencv3
- squeezelite
- tovid
Even if it selects ffmpeg, Kodi does not need an update since Kodi is
only available on a limited number of architectures (which don't
include nios2, obviously). Other packages only make use of ffmpeg when
available.

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.

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.

Currently, we only support either Qt4 or gtk2, but OpenCV also
additionally supports Qt5 or gtk3, making for a choice of four
toolkits, one of: Qt4, Qt5, gtk3, gtk2 (and obviously, none).
Since Buildroot does not support coexistence of Qt4 and Qt5, we
can no longer select one and depend on the other, like so:
config BR2_PKG_OCV_WITH_QT4
bool "Qt4"
depends on !BR2_PKG_QT5
select BR2_PKG_QT
config BR2_PKG_OCV_WITH_QT5
bool "Qt5"
depends on !BR2_PKG_QT
select BR2_PKG_QT5
otherwise, we'd get a circular dependency chain in Kconfig, which would
complain with:
package/opencv/Config.in:57:error: recursive dependency detected!
package/opencv/Config.in:57: choice <choice> contains symbol BR2_PKG_OCV_WITH_QT5
package/opencv/Config.in:111: symbol BR2_PKG_OCV_WITH_QT5 depends on BR2_PKG_QT
package/qt/Config.in:5: symbol BR2_PKG_QT is selected by BR2_PKG_OCV_WITH_QT
package/opencv/Config.in:98: symbol BR2_PKG_OCV_WITH_QT is part of choice <choice>
Instead, we need to depend on either Qt version.
So, to have a consistent choice, we make all support for GUI toolkits
actually depend on the toolkit, rather than select it.

Now that OpenCV inter-module dependencies are correctly set at the

OpenCV allows to enable/disable the selection of modules (a.k.a.
opencv libraries). These modules depend one on the others; these
dependencies are already handled by the build-system (CMake).
However, the way we handled them in Buildroot was not really clean.
For each opencv module, there is a kconfig option, but we forced the
corresponding CMake config option without checking for the modules'
dependencies.
This patch replicates the modules' dependency relations in the
Config.in, so that the selection of the user will actually be built.

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.
