Log message:
	[hpux/ttrace] Determine attached process LWP immediately after attaching.
	
	When attaching to a process, the ttrace interface was creating a ptid
	with a null LWP, because it did not have it yet.  This LWP was then
	set as soon as we received our first event from our inferior, during
	our first wait.  Similarly, the allocation of the thread private info
	was also defered.
	
	This works on PA/HP-UX, because we immediately perform a wait to pop
	the event triggered by the attach.  We can use that event to extract
	the thread's LWP.  But this does not work for IA64/HP-UX, because
	the attach no longer triggers an event, and thus a wait should NOT
	be performed (such a wait would simply block indefinitely).
	
	It is actually possible, however, to determine the thread's LWP.
	This change therefore adjusts the attach code to create a thread with
	the correct LWP set, as well as with its private info allocated.
	Same thing for all the other threads.
	
	gdb/ChangeLog:
	
	[ttrace] Compute thread list immediately after attach.
	* inf_ttrace_attach (inf_ttrace_create_threads_after_attach):
	New subprogram.
	(inf_ttrace_attach): Use it.
