* target.h: Add to_insert_hw_breakpoint, to_remove_hw_breakpoint,

Browse Source 
to_insert_watchpoint, to_remove_watchpoint,
	to_stopped_by_watchpoint, to_stopped_data_address,
	to_region_size_ok_for_hw_watchpoint, to_can_use_hw_breakpoint to
	target vecctor. Define their corresponding macros so they call
	them.

	* target.c: Add default and debug versions of for
	to_insert_hw_breakpoint, to_remove_hw_breakpoint,
	to_insert_watchpoint, to_remove_watchpoint,
	to_stopped_by_watchpoint, to_stopped_data_address,
	to_region_size_ok_for_hw_watchpoint, to_can_use_hw_breakpoint.
