Based on work by Jan Kratochvil <jan.kratochvil@redhat.com> and Jeff
Johnston <jjohnstn@redhat.com>.
* NEWS: Mention attach to stopped process fix.
* infcmd.c (detach_command, disconnect_command): Discard the thread
list.
* infrun.c (handle_inferior_event): Do not ignore non-SIGSTOP while
attaching. Use signal_stop_state.
(signal_stop_state): Check stop_soon.
* linux-nat.c (kill_lwp): Declare earlier.
(pid_is_stopped, linux_nat_post_attach_wait): New.
(lin_lwp_attach_lwp): Use linux_nat_post_attach_wait. Update
comments.
(linux_nat_attach): Use linux_nat_post_attach_wait.
(detach_callback, linux_nat_detach): Improve handling for signalled
processes.
(linux_nat_pid_to_str): Always print out the LWP ID if it differs
from the process ID.
* Makefile.in (infcmd.o): Update.
