  Issue 846388. Adds a call to PyErr_CheckSignals to
  SRE_MATCH so that signal handlers can be invoked during
  long regular expression matches.  It also adds a new
  error return value indicating that an exception
  occurred in a signal handler during the match, allowing
  exceptions in the signal handler to propagate up to the
  main loop.  Thanks Josh Hoyt and Ralf Schmitt.
