Fake VFORK_DONE events when following only the parent after a vfork.
FreeBSD does not currently report a ptrace event for a parent process
after it resumes due to the child exiting the shared memory region after
a vfork. Take the same approach used in linux-nat.c in this case of
sleeping for a while and then reporting a fake VFORK_DONE event.
gdb/ChangeLog:
* fbsd-nat.c (struct fbsd_fork_child_info): Rename to ...
(struct fbsd_fork_info): ... this.
(struct fbsd_fork_info) <child>: Rename to ...
(struct fbsd_fork_info) <ptid>: ... this.
(fbsd_pending_children): Update type.
(fbsd_remember_child): Update type and field name.
(fbsd_is_child_pending): Likewise.
(fbsd_pending_vfork_done): New variable.
(fbsd_is_vfork_done_pending): New function.
(fbsd_next_vfork_done): New function.
(fbsd_resume): Don't resume processes with a pending vfork done
event.
(fbsd_wait): Report pending vfork done events.
(fbsd_follow_fork): Delay and record a pending vfork done event
for a vfork parent when detaching the child.
