The cmake configuration option HARD_REALTIME was added. This sets or
unsets the compile time variable EMBB_HARD_REALTIME.

(Merge was previously reverted accidentally. Re-applying merge to fix this.)

This reverts commit 554c76f7, reversing
changes made to fc660db0.

This reverts commit 40624201.

Put printing the automatic initialization message to the main CMakeLists.txt file, as this is more logical

Modified tests, to only execute opencl tests when opencl project was build with opencl. This involves also generating test batch files completely, therefore tests executables need no longer to be added manually to the respective batch files.

Build opencl module, examples and tests only if opencl is available in the build environment. Tested with environment, not having opencl installed.

- Rename run_tests_linux.sh to run_tests_unix.sh
- Use /bin/sh instead of bash

The old version depended on the build-dir to be a subdirectory of the
source directory.
With this patch one can build in tree or put the build-dir anywhere.
