* infrun.c (normal_stop, proceed): Remove call to print_sys_errmsg

when breakpoints fail. Move general breakpoint error messages to
	insert_breakpoints.
	* breakpoint.c (insert_breakpoints): Change warnings when
	breakpoints are nto inserted to specify the type. Remove call to
	memory_error when hardware breakpoints can't be inserted. Remove
	multiple calls to warning so all messages are sent to the user at
	once.
	(delete_breakpoints): Make insert error messsages more explicit.
