Revert previous delta, which is not required with rev 1.5 of
src/contrib/gcc/c-format.c .

Set WFORMAT=0, because our compiler currently complains about NULL
arg 2 to err() and friends, and warnings are promoted to errors.

This allows the following revisions to be reverted:

rev 1.39 src/bin/cp/cp.c
rev 1.26 src/bin/chmod/chmod.c
rev 1.40 src/bin/rm/rm.c

The following revisions can already be reverted, because they were
already covered by WFORMAT=0:

rev 1.8 src/bin/ls/lomac.c
rev 1.63 src/bin/ls/ls.c
rev 1.8 src/bin/ps/lomac.c
rev 1.34 src/bin/rcp/rcp.c

Fix warnings inspired by lint, a commercial lint and WARNS=4.

Default to WARNS=2. Binary builds that cannot handle this must explicitly
set WARNS=0.

$Id$ -> $FreeBSD$

Add -W and fix the warning due to missing struct initializer

Use mmap for file coping. 5-10% faster than the read system call.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
