Olivier Parcollet 446f817111 wrapper: add release_GIL_and_enable_signal option.
- 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.
