This commit adds initial support for catchpoints to the python breakpoint API. This commit adds a BP_CATCHPOINT constant which corresponds to GDB's internal bp_catchpoint. The new constant is documented in the manual. The user can't create breakpoints with type BP_CATCHPOINT after this commit, but breakpoints that already exist, obtained with the `gdb.breakpoints` function, can now have this type. Additionally, when a stop event is reported for hitting a catchpoint, GDB will now report a BreakpointEvent with the attached breakpoint being of type BP_CATCHPOINT - previously GDB would report a generic StopEvent in this situation. gdb/ChangeLog: * NEWS: Mention Python BP_CATCHPOINT feature. * python/py-breakpoint.c (pybp_codes): Add bp_catchpoint support. (bppy_init): Likewise. (gdbpy_breakpoint_created): Likewise. gdb/doc/ChangeLog: * python.texinfo (Breakpoints In Python): Add BP_CATCHPOINT description. gdb/testsuite/ChangeLog: * gdb.python/py-breakpoint.c (do_throw): New function. (main): Call do_throw. * gdb.python/py-breakpoint.exp (test_catchpoints): New proc.
