[patch/rfc] Deprecate CHILD_RESUME and KILL_INFERIOR

[Andrew Cagney <cagney at gnu dot org>]

Hello,

Following up on:
http://sources.redhat.com/ml/gdb-patches/2004-09/msg00093.html

this deprecates several of the macros used by infptrace.c / inftarg.c 
(there are more, these were easy and serve as an illustration).

Code can now instead, as illustrated by PPC/NetBSD (ppcnbsd-nat.c), use 
inf_ptrace_target (or inf_child_target) to construct the target vector 
and then register it directly.

I'll look to commit this in a week.
Andrew
