always throw exception after debugging with debug_on_error
* quit.h (octave_execution_exception::set_stack_trace (void)):
New overloaded function.
* error.h, error.cc (maybe_enter_debugger): Rename from
debug_or_throw_exception. Just handle debugging. Display stack trace
from exception object instead of calling pr_where. If stack trace is
printed, clear stack trace info from exception object. Pass object as
non-const reference.
(usage_1, error_1): Throw execption after call to maybe_enter_debugger.
Pass exception object by non-const reference.
(verror, error): Pass exception object by non-const reference.
* gripes.h, gripes.cc (gripe_user_supplied_eval,
gripe_wrong_type_arg): Pass exception object by non-const reference.
* __qp__.cc, daspk.cc, dasrt.cc, dassl.cc, data.cc, file-io.cc,
graphics.cc, graphics.in.h, lsode.cc, oct-handle.h, oct-map.cc,
quad.cc, rand.cc, toplev.cc, __eigs__.cc, ov-base.cc, ov.cc,
oct-parse.in.yy: Catch octave_execution_exception as non-const
reference as needed.
