Merge in NetBSD mods and -Wall cleaning.

Fix for PR#1287. This makes sh behave sensibly in case statements in the
face of aliases. Note, bash doesn't do aliases while running scripts, but

Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a
merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault... mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do. The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..

a few new files appearing. I dont think they are a problem)
