to the inner most containing exception handler (established using
catch_exceptions() or the legacy catch_errors()).
Useful when a section of code that caught an exception finds it
needs to repropagate that exception up the call chain.
The name return_to_top_level() dates back to a time when GDB had
only one exception handler installed at the top level. This really
did return to the top level. The name should probably be changed.
NOTE: Some sections of code are using error_begin() in conjunction
with return_to_top_level() to throw the initial exception. That
code should, instead, use either error() or error_string(). */
