Implement most breakpoint_ops methods for all breakpoint types,
	and move the default handlings to the proper callbacks.

	gdb/
	* breakpoint.c (update_watchpoint): Always call the breakpoint's
	works_in_software_mode method.
	(insert_bp_location): Go through breakpoint_ops->insert_location
	for software and hardware watchpoints.
	(create_internal_breakpoint): Pass bkpt_breakpoint_ops as
	breakpoint_ops.
	(remove_breakpoint_1): Go through breakpoint_ops->remove_location
	for software and hardware watchpoints.
	(print_it_typical): Delete.
	(print_bp_stop_message): Always call the breakpoint_ops->print_it
	method.
	(watchpoint_check): Adjust comment.
	(bpstat_check_location): Simply always call the breakpoint's
	breakpoint_hit method.
	(bpstat_stop_status): Always call the breakpoint's check_status
	method.  Remove special cases for watchpoints and internal event
	breakpoints from here (moved to the check_status implementations).
	(print_one_breakpoint_location): Assume b->ops is never NULL.
	Remove static tracepoint marker id printing from here (moved to
	the print_one_detail callback implementation of tracepoints).
	(init_bp_location): Assert OPS is never NULL.
	(allocate_bp_location): Always call the breakpoint's
	allocate_location method, and remove the default code from here.
	(free_bp_location): Always call the location's dtor method, and
	remove the default code from here.
	(init_raw_breakpoint_without_location): Assert OPS is never NULL.
	(set_raw_breakpoint_without_location): Add new breakpoint_ops
	parameter.  Pass it down.
	(set_raw_breakpoint): Ditto.
	(print_it_catch_fork): Adjust to take a bpstat as argument.
	(catch_fork_breakpoint_ops): Install methods.
	(print_it_catch_vfork): Adjust to take a bpstat as argument.
	(catch_vfork_breakpoint_ops): Install methods.
	(dtor_catch_syscall): Call the base dtor.
	(print_it_catch_syscall): Adjust to take a bpstat as argument.
	(catch_syscall_breakpoint_ops): Install methods.
	(dtor_catch_exec): Call the base dtor.
	(print_it_catch_exec): Adjust to take a bpstat as argument.
	(catch_exec_breakpoint_ops): Install methods.
	(hw_breakpoint_used_count, hw_watchpoint_used_count): Always call
	the breakpoint's resources_needed method, and remove the default
	code from here.
	(set_momentary_breakpoint): Pass bkpt_breakpoint_ops as
	breakpoint_ops.
	(clone_momentary_breakpoint): Clone the original's ops.
	(mention): Always call the breakpoint's print_mention method, and
	remove the default code from here.
	(create_breakpoint_sal): Adjust to pass the ops to
	set_raw_breakpoint rather than setting it manually.
	(create_breakpoint): Assert ops is never NULL.  Adjust to pass the
	ops to set_raw_breakpoint_without_location rather than setting it
	manually.
	(break_command_1): Pass bkpt_breakpoint_ops as breakpoint_ops.
	(print_it_ranged_breakpoint): Adjust to take a bpstat as argument.
	(ranged_breakpoint_ops): Install methods.
	(break_range_command): Adjust to pass the ops to
	set_raw_breakpoint rather than setting it manually.
	(re_set_watchpoint, breakpoint_hit_watchpoint)
	(check_status_watchpoint, resources_needed_watchpoint)
	(works_in_software_mode_watchpoint, print_it_watchpoint)
	(print_mention_watchpoint, print_recreate_watchpoint): New
	functions.
	(watchpoint_breakpoint_ops): Install new methods.
	(print_it_masked_watchpoint): New function.
	(masked_watchpoint_breakpoint_ops): Install new methods.
	(watch_command_1): Adjust to pass the right breakpoint_ops to
	set_raw_breakpoint_without_location rather than setting it
	manually later.  Record the current pspace.

	argument.
	(gnu_v3_exception_catchpoint_ops): Install new methods.

	to create_breakpoint.
	(save_breakpoints): Always call the breakpoint's print_recreate
	method, and remove the default handling from here.
