2015-03-24Make linux_stop_lwp be a shared functionGary Benson1-0/+5

This commit introduces a new function, iterate_over_lwps, that shared Linux code can use to call a function for each LWP that matches certain criteria. This function already existed in GDB and was in use by GDB's various low-level Linux x86 debug register setters.
