dbstop: conditional breakpoint, dbstop if caught error etc. (bug #46795)
* debug.cc (parse_dbfunction_params): Accept "in", "at" and "if" tokens.
Only breakpoints are returned; "dbstop if error" etc. are processed in
the parser.
* debug.cc (dbstop_process_map_ags, Fdbstop): set breakpoints etc. based on the
output of A=dbstatus. The structure of A is not Matlab compatible.
* debug.cc (do_add_breakpoint_1, do_get_breakpoint_list): Store file
(not subfunction) names in bp_set, to avoid crash in "dbclear all".
* debug.cc (dbclear_all_signals, condition_valid,
stop_on_err_warn_status): New function
* debug.cc (do_add_breakpoint): take "condition" parameter.
* debug.cc (do_get_breakpoint_list): Make invariant copy of bp_set (bug #44195)
* debug.cc (do_add_breakpoint, do_remove_breakpoint,
do_remove_all_breakpoints_in_file): More informative error messages.
* debug.cc (Fdbclear): clear break on signals (error, warning etc.)
* debug.cc (Fdbstatus): Return all breakpoints when debugging, so that
"s = dbstatus; ...; dbstop (s)" works.
(Related to bug #41338, bug #41556)
* debug.cc (Fdbstatus): Return structure with conditions, and "if error" etc.
* debug.h (debug_on_err, debug_on_caught, debug_on_warn): New functions
* debug.h: Rename "fname_line_map" to "fname_bp_map", as it has conditions
* error.cc (verror): Allow dbstop on selected errors, or errors in try/catch
* error.h New globals: Vdebug_on_caught, in_try_catch.
* toplev.cc: Experimental code for Matlab's "dbstop if naninf".
* symtab.cc (load_class_constructor): Add class constructors to list of
methods so they can be breakpointed
* pt-pb.{cc,h} (take_action): Add "condition" to set_breakpoint call,
track bp_cond_list.
* pt-eval.cc visit_.*_command: Ask if breakpoint condition is satisfied.
* pt-eval.cc (visit_try_catch_command): Count the number of levels of
try/catch we are in to allow "dbstop if caught error".
* pt-stmt.cc (set_breakpoint): Pass condition
* pt-stmt.cc (is_breakpoint): If new argument is true, only return true
if the condition is set.
* pt-stmt.cc (bp_cond, preakpoints_and_conds): new function
* pt-stmt.h: new declarations
* pt.{cc,h} (meets_bp_condition, bp_cond): New function
* octave-link.h (update_breakpoint): Accept condition
