	* gdbthread.h (struct thread_info): New `pending_follow' field.
	* thread.c (new_thread): New function.
	(add_thread_silent): Use it.
	* breakpoint.c (internal_breakpoint_number): New global, moved
	from inside...
	(create_internal_breakpoint): ... this.
	(clone_momentary_breakpoint): New.
	* breakpoint.h (clone_momentary_breakpoint): Declare.
	* infrun.c (nullify_last_target_wait_ptid): Move declaration
	higher.
	(pending_follow): Delete.
	(follow_fork): Handle pending follow fork event here.  Moved the
	preserving of thread stepping state here.
	(resume): Don't handle pending follow fork events here.  Only
	install the inferior's terminal modes if we're about to resume it.
	(proceed): Handle possible pending follow fork events here.
	(init_wait_for_inferior): No need to clear pending_follow anymore,
	it's gone.
	(handle_inferior_event): Adjust to per-thread `pending_follow'.
	Call `follow_fork' to handle following the fork.  If the
	follow-fork is cancelled, stop stepping.
	* linux-nat.c (linux_child_follow_fork): Adjust to per-thread
	`pending_follow' events.  Remove code that handled preserving the
	thread stepping state.
	* inf-ptrace.c (inf_ptrace_follow_fork): Ditto.
	* inf-ttrace.c (inf_ttrace_follow_fork): Ditto.
