* Add HPX backend for OpenCV implementation
Adds hpx backend for cv::parallel_for_() calls respecting the nstripes chunking parameter. C++ code for the backend is added to modules/core/parallel.cpp. Also, the necessary changes to cmake files are introduced.
Backend can operate in 2 versions (selectable by cmake build option WITH_HPX_STARTSTOP): hpx (runtime always on) and hpx_startstop (start and stop the backend for each cv::parallel_for_() call)
* WIP: Conditionally include hpx_main.hpp to tests in core module
Header hpx_main.hpp is included to both core/perf/perf_main.cpp and core/test/test_main.cpp.
The changes to cmake files for linking hpx library to above mentioned test executalbles are proposed but have issues.
* Add coditional iclusion of hpx_main.hpp to cpp cpu modules
* Remove start/stop version of hpx backend
- allow installing samples sources on all platforms
even if BUILD_EXAMPLES is disabled, fixed minor
issues in sources installation process
- use 'example_<group>_<name>' scheme for target and binary file naming
- use single function for sample executable creation
* Do not build protobuf if dnn is disabled
* Added BUILD_LIST cmake option to the cache
* Moved protobuf to the top level
* Fixed static build
* Fixed world build
* fixup! Fixed world build
- use suffixes like '.avx.cpp'
- added CMake-generated files for '.simd.hpp' optimization approach
- wrap HAL intrinsic headers into separate namespaces for different build flags
- automatic vzeroupper insertion (via CV_INSTRUMENT_REGION macro)

bb1c2d7 fix bug on border at pyrUp
The INSTALL_NAME_DIR property of a target specifies how a dynamic library should
be found on OS X. If INSTALL_NAME_DIR is not specified the loader will search
relative to the standard search paths. If specified it should either be
an absolute path or relative path prefixed with either @executable_path,
@load_path, or @rpath. Specifying "lib" does not make sense here and
causes linking error as documented here:
http://answers.opencv.org/question/4134/cmake-install_name_tool-absolute-path-for-library-on-mac-osx/
and here
http://stackoverflow.com/questions/26978806/dyld-library-not-loaded-lib-libopencv-core-3-0-dylib-reason-image-not-found
This patch removes INSTALL_NAME_DIR everywhere it is set to "lib".
An alternate solution would be to set an absolute path like
"${CMAKE_INSTALL_PREFIX}/lib" or relative path like
"@executable_path/../lib". However, if there is not specific need for
specifying a path, it is probably best left unset.
