begin removal of global error_state variable
* gripes.h, gripes.cc (gripe_library_execution_error): Delete.
* error.cc (warning_state): Delete unused variable.
(reset_error_handler): Don't set warning_state or error_state.
(debug_or_throw_exception): New static function.
(verror): Don't check error_state.
(vmessage): Call debug_or_throw_exception instead of setting
error_state.
(error_1, error_2): Combine into single function, error_1 that prints
error message and ultimately calls debug_or_throw_exception.
(verror, verror_with_cfn, verror_with_id_cfn): Call error_1. Don't
check or set warning_state.
(error): Don't check error_state.
(Flasterror, Flasterr): Adapt to not using error_state.
(interpreter_try): Don't unwind_protect error_state.
* NEWS: Update.
* doc/interpreter/external.txi: Explain octave_execution_exception
instead of error_state for matrix addition example.
* jit-typeinfo.cc (octave_jit_gripe_nan_to_logical_conversion,
octave_jit_ginvalid_index, octave_jit_gindex_range,
octave_jit_paren_scalar, octave_jit_paren_scalar_subsasgn):
Don't catch octave_execution_exception.
* cellfun.cc (Fcellfun): Use exceptions instead of error_state.
* ls-mat-ascii.cc (save_mat_ascii_data): Likewise.
* mex.cc (mexCallMATLAB, mexEvalString): Likewise.
* variables.cc (safe_symbol_lookup): Likewise.
* svd.cc (Fsvd): Eliminate use of error_state.
* __magick_read__.cc (read_file, write_file): Likewise.
* variables.cc (generate_struct_completions): Eliminate use of
obsolete warning_state variable.
* ov-builtin.cc (octave_builtin::do_multi_index_op): Don't catch
octave_execution_exception and call gripe_library_execution_error.
* ov-class.cc (octave_class::reconstruct_exemplar): Eliminate use of
error_state. Catch possible octave_execution_exception in
do_multi_index_op.
* ov-mex-fcn.cc (octave_mex_function::do_multi_index_op): Eliminate
use of error_state. Catch possible octave_execution_exception in
call_mex.
* ov-fcn-handle.cc (octave_fcn_binder::maybe_binder): Eliminate use of
error_state.
* ov-oncleanup.cc (octave_oncleanup::~octave_oncleanup): Eliminate use
of error_state. Propagate possible octave_execution_exception from
do_multi_index_op.
* ov.cc (octave_value::assign, do_binary_op, do_unary_op,
octave_value::do_non_const_unary_op): Don't catch
octave_execution_exception here.
* oct-parse.in.yy (octave_base_parser::finish_colon_expression,
octave_base_parser::finish_array_list): Eliminate use of warning_state
and error_state.
(Feval, Fevalin): Use exceptions instead of error_state.
* pt-eval.cc, pt-eval.h (tree_evaluator::unwind_protect_exception):
New static variable.
* (tree_evaluator::visit_statement): Don't catch
octave_execution_exception here.
(tree_evaluator::visit_try_catch_command,
tree_evaluator::do_unwind_protect_cleanup): Eliminate use of error_state.
(tree_evaluator::visit_unwind_protect_command): Use
unwind_protect_exception to track whether an exception has occurred in
the try block.
