config/ns32k/ns32km3.mh: Define NAT_FILE.
* config/nm-m3.h: Change guard from _OS_MACH3_H_ and _OS_MACH3_H
(it was inconsistent and namespace-wrong) to NM_M3_H.
* m3-nat.c (mach_really_wait): Change parameter name to ourstatus.
(m3_open): New function.
(m3_ops): Use it.
* TODO: Update Mach section.
* Makefile.in: Remove "rapp" stuff; it is superseded by gdbserver.
config/mips/{mipsm3.mt,mipsm3.mh},
config/ns32k/{ns32km3.mt,ns32km3.mh}: Use correct names for TM_FILE
and XM_FILE. Replace host files *mach3-xdep.o with native
files *m3-nat.o. Replace host file os-mach3.o with native
file m3-nat.o.
* config/i386/i386mach.c: Explain this is for the old (probably
non-functional and/or obsolete) Mach stuff.
