Include patchlevel in directory name of documentation install in Linux
- Check for Doxyfile.in. If not present, do not add doxygen target (fixes internal issue #221)
- Omit doxygen "Makefiles" from tarball (internal issue #221)
- Add executable flag to shell scripts (fixes internal issue #224)
Fix internal issue #214, change default doxygen label for api to two (using javascript to collapse to that level)

mtapi_c: fixed internal issue #220 (Fix typo "ids_availabe" in struct member)
dataflow_cpp: fixed missing include when compiling with clang
.travis.yml: initial version for travis-ci
Fixed bug due to Hazard Pointer.
HelpScan was implemented wrong -> Scan could be executed be different threads the same time -> FixedSize lists got messed up -> program tried to return wrong pointers to the object pool -> segfault or hang

Moreover, added assertion that checks that only one thread concurrently enters scan, for avoiding these kind of bugs in the future.

Remove warnings (gcc):
- shift initialization of is_active to correct position
- remove unused variable
