Task #7519: Put LOGGER_ENTER_THREAD and LOGGER_EXIT_THREAD into a struct, and use it in Cobalt to do proper C++ RAII. Reason is to also use it in APERTIF. Trivial; compile tested.

Task #7490: reintegrate merge with the trunk. All Online_Cobalt tests pass. ('Move createStream from RTCP to LCS Stream and clean up')

Task #7490: fix tTABTranspose for patched SocketStream. Strictly speaking, the now patched aspect was already wrong in the test.

Also:
- Move deadline check from createStream() into SocketStream().
- Get rid of unused code in an old attempt by me to refactor createStream().
- Fix inverted check > 0 vs < 0 on one of the 2 usleep()s to back-off connect() in SocketStream().
- Move EndOfStreamException and TimeOutException out of their classes (and fix up users).
- Replace readdir() by readdir_r(). Probably irrel since only retval checked vs 0.
- Clarify ~FileDescriptorBasedStream() somewhat, only delay cancellation if actually calling close().
- Constify a few local vars in SocketStream.cc.

Reason: In APERTIF, we need to receive UDP frames from the FPGA correlator.
We can live with LOFAR Common and Stream, but prefer not to have CoInterface just for createStream().
(All other network communication will be done via QPID messaging middleware.)

Build tested only.

New version was accidently committed.
However, it is the question why it fails on LCU, but is fine on CEP2/3.

Added new packages to LofarPackageList.cmake

Added dynamically loadable Python DPPP step

Task #1254: Bug fix to FindPyrap.cmake. If Pyrap is not required, then casacore should also not be required.

Needed to install a few header files

Merged NDPPP-Task6225 branch on the trunk

Jan David agreed it makes sense, although some software covered is not
currently maintained by the RO software team.
All replacements happen in comments, so this is safe. (viewed svn diff | grep ... by hand)
Command used:
LOFAR$ grep -r -l seg@astron.nl * | xargs sed -i -e 's/seg@astron.nl/softwaresupport@astron.nl/g'

Task #7064: Moved DE609 from cbm005.eth5 -> cbm008.eth5, and moved RS307 from cbm008.eth5 -> cbm008.eth2

Task #7384: Reintegrated branch (CMake: FindCasacore.cmake component list is not up-to-date) with the trunk.

Task #7384: The two tSocketConnection tests in CEP/LMWCommon must be run serially, because they use the same resources.

Task #7384: Updated the component dependencies in the FindCasacore macro to match with casacore release 1.7.0.

Task #7384: Added a script to generate casacore component dependencies that can be copied/pasted into the FindCasacore.cmake macro.
