gdb: use intrusive_list for linux-nat lwp_list

Browse Source 
Replace the manually maintained linked list of lwp_info objects with
intrusive_list.  Replace the ALL_LWPS macro with all_lwps, which returns
a range.  Add all_lwps_safe as well, for use in iterate_over_lwps, which
currently iterates in a safe manner.
