- Add to the wrapper generator (add_method) the release_GIL_and_enable_signal option which : - release the GIL - save the python signal handler - enable the C++ triqs signal handler instead. - undo all of this after the code runs, or in a case of exception. - used python include, ceval.h, line 72 comments and below. - reworked the triqs::signal_handler. simple C like function, no object (no need). start, stop, received, cf header file. - clean the call_back.cpp : only place using the signal directly (qmc uses the callback). in particular, remove the old BOOST CHRONO, since the std::chrono works fine on platforms we use now.
