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..

sh: Constify various strings.

Most of this is adding const keywords, but setvar() in var.c had to be
changed somewhat more.

- Merge from HEAD

be more type correct and align local ckmalloc() with its underlying malloc(3) by using a "size_t" instead of an "int" argument

- Apply the r190270 changes to printing of single aliases too.
- Sort the aliases before printing them.

Make the output of the alias built-in POSIX-compliant: Drop the leading 'alias'
and suppress printing the trailing space which is added for internal purposes.

use 'const' for the parameters of the two static functions unalias() and hashalias()

remove an unnecessary include

Return 1 from the unalias builtin if _any_ removal fails, not just the last
one.

Use prototypes in the MKINIT lines collected by mkinit.

Remove clause 3 from the UCB licenses.
