changed signature of DoocsProcessScalar to accept a different name for the Doocs property than the PV name

factored out the actual importing into a function with a plain C++ interface so it can be used without XML file

refactoring: merged processLocationImport and processGlobalImport into one function as they were 90 % idendical

implemented tests are now checking for the correct expected values (and still failing due to missing implementation

fixed problems with the rpath: rpath on installed library was not set; tests were using installed DoocsAdapter instead of library from build directory

necessary update for latest change in the ControlSystemAdapter interface (removal of deprecated functions)

properly compute the length of the DOOCS property name when deciding whether to enable history for it or not

disable history for properties with names longer than 64 characters, since DOOCS seems not to support this
