* gdbthread.h (ALL_THREADS): New macro.
(thread_list): Declare.
* infrun.c (handle_inferior_event) <spurious signal>: Don't keep
going, but instead fall through to the stepping handling.
* linux-nat.c (resume_lwp): New parameter 'signo'. Resume with
the passed in signal. Adjust debug output.
(resume_callback): Rename to ...
(linux_nat_resume_callback): ... this. Pass the thread's last
stop signal, if in "pass" state.
(linux_nat_resume): Adjust to rename.
(stop_wait_callback): New assertion. Don't respawn signals;
instead let the LWP remain with SIGNALLED set.
(linux_nat_wait_1): Remove flushing of pending SIGSTOPs.
* remote.c (append_pending_thread_resumptions): New.
(remote_vcont_resume): Call it.
* target.h (target_resume): Extend comment.
