	Implement support for PowerPC BookE masked watchpoints.
	
	gdb/
	* NEWS: Mention masked watchpoint support.  Create "Changed commands"
	section.
	* breakpoint.h (struct breakpoint_ops) <works_in_software_mode>: New
	method.  Initialize to NULL in all existing breakpoint_ops instances.
	(struct breakpoint) <hw_wp_mask>: New field.
	* breakpoint.c (is_masked_watchpoint): Add prototype.
	(update_watchpoint): Don't set b->val for masked watchpoints.  Call
	breakpoint's breakpoint_ops.works_in_software_mode if available.
	(watchpoints_triggered): Handle the case of a hardware masked
	watchpoint trigger.
	(watchpoint_check): Likewise.
	(works_in_software_mode_watchpoint): New function.

	(print_one_detail_masked_watchpoint, print_mention_masked_watchpoint)
	(print_recreate_masked_watchpoint, is_masked_watchpoint): New
	functions.
	(masked_watchpoint_breakpoint_ops): New structure.
	(watch_command_1): Check for the existence of the `mask' parameter.

	* ppc-linux-nat.c (ppc_linux_insert_mask_watchpoint)
	(ppc_linux_remove_mask_watchpoint)
	(ppc_linux_masked_watch_num_registers): New functions.
	(_initialize_ppc_linux_nat): Initialize to_insert_mask_watchpoint,
	to_remove_mask_watchpoint and to_masked_watch_num_registers.
	* target.c (update_current_target): Mention to_insert_mask_watchpoint,
	to_remove_mask_watchpoint, and to_masked_watch_num_registers.
	(target_insert_mask_watchpoint, target_remove_mask_watchpoint)
	(target_masked_watch_num_registers): New functions.
	* target.h (struct target_ops) <to_insert_mask_watchpoint>,
	<to_remove_mask_watchpoint>, <to_masked_watch_num_registers>: New
	methods.
