Backport PR : safe_run_module: Silence SystemExit codes 0 and None....

Backport PR : safe_run_module: Silence SystemExit codes 0 and None. In `safe_execfile` we ignore SystemExit exceptions with codes 0 and 1. We don't do this for `safe_run_module` which leads to the following mismatch of tracebacks between Python and IPython: ``` $ cat > exit0.py import sys sys.exit(0) $ python -m exit0 $ ipython -m exit0 --------------------------------------------------------------------------- SystemExit Traceback (most recent call last) /usr/lib/python2.7/runpy.pyc in run_module(mod_name, init_globals, run_name, alter_sys) 174 if alter_sys: 175 return _run_module_code(code, init_globals, run_name, --> 176 fname, loader, pkg_name) 177 else: 178 # Leave the sys module alone /usr/lib/python2.7/runpy.pyc in _run_module_code(code, init_globals, mod_name, mod_fname, mod_loader, pkg_name) 80 mod_globals = temp_module.module.__dict__ 81 _run_code(code, mod_globals, init_globals, ---> 82 mod_name, mod_fname, mod_loader, pkg_name) 83 # Copy the globals of the temporary module, as they 84 # may be cleared when the temporary module goes away /usr/lib/python2.7/runpy.pyc in _run_code(code, run_globals, init_globals, mod_name, mod_fname, mod_loader, pkg_name) 70 __loader__ = mod_loader, 71 __package__ = pkg_name) ---> 72 exec code in run_globals 73 return run_globals 74 /tmp/exit0.py in <module>() 1 import sys ----> 2 sys.exit(0) SystemExit: 0 WARNING: Unknown failure executing module: <exit0> ``` The attached pull request silences SystemExit exceptions with codes 0 and None.

      """Utilities to enable code objects to be pickled.

      Any process that import this module will be able to pickle code objects.  This

      includes the func_code attribute of any function.  Once unpickled, new

      functions can be built using new.function(code, globals()).  Eventually

      we need to automate all of this so that functions themselves can be pickled.
