[commit] Add notify inferior-created calls

[Andrew Cagney <cagney at gnu dot org>]

Hello,

Ref: http://sources.redhat.com/ml/gdb-patches/2004-05/msg00169.html

This patch adds the needed calls to notify inferior-created observers of 
that event (now that from_tty is available where needed).

I've covered all the cases I could identify while testing GDB on 
GNU/Linux native.  I suspect, due to the way GDB is currently 
structured, that further calls may need to be scattered through the 
code.  That can be done on an as-identified basis (unless I happen to 
re-structure GDB fixing this problem first :-).

committed,
Andrew

	* inftarg.c: Include "observer.h".
	(child_attach, child_create_inferior): Notify inferior_created.
	* corelow.c: Include "observer.h".
	(core_open): Notify inferior_created.
	* Makefile.in (inftarg.o, corelow.o): Update
	dependencies.
