Factorized  hdl/common/DUTInterfaces_rtl.vhd to put hand-shake specific ( EUDET/AIDA ) code into hdl/common/DUTInterface_AIDA_rtl.vhd and hdl/common/DUTInterface_EUDET_rtl.vhd.

N.B. DUTInterface_EUDET_rtl.vhd not yet tested. DUTInterface_AIDA_rtl.vhd runs in simulation.

Improved Doxygen comments in coincidenceLogic_rtl.vhd , hdl/common/synchronizeRegisters_rtl.vhd ,  hdl/common/triggerLogic_rtl.vhd

Increased number of DUTs in simulation_src/fmc-tlu_v0-1_test-bench.vhd from 2 to 3.
