Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Rename mail(1)'s aux.c to util.c.

The name `aux' is reserved on Windows file systems. aux.c in the mail(1)
directory contains some random utility functions. I'm renaming this file
to util.c to make it possible to check out this directory on Windows.

MFC after: 1 month

Drop support for COPY, -c has been the default mode of install(1)
for a long time now.

s/${INSTALL} -c/${INSTALL} ${COPY}/

Remove NO_WERRORs and WARNS=n's. To be revisited after GCC3.

Link mail(1) to mailx per POSIX. Mail(1) isn't 100% POSIX compliant,
but it is pretty close.

Not objected to by: -standards

Install files via FILES.

I'm working on cleaning this up, however it probably won't be done for
awhile. Turn off WARNS so that this doesn't break the build when WARNS
is turned on higher up. Also add $FreeBSD$.

make install should not install mail.rc in /etc

Simplistic conversion of mail to use termios instead of sgtty.

Change `install' to `${INSTALL}' so that default install flags can be
specified in the top level Makefiles.

Remove -R from CFLAGS
