Cleanup mail(1)'s varying styles by converting to using style(9).

Also take a stab at cleaning up BDECFLAGS and convert all uses of
NOSTR, NIL, NONE, NOVAR, NOGRP, NOGE to NULL. Also kill 'register' to
get diffs somewhat closer to OpenBSD/NetBSD.

There are no functional changes however.

Ignore the MAIL environment variable when the -u flag is set.

PR: bin/8665

Teach boring old mail(1) about the use of the REPLYTO environment
variable which is de-facto standard for MUAs.

Teach bomail to generate an in-reply-to header so threading MUAs and
mail->news gateways won't lose context.

While i was at it, removed two gratuitous standard violations for
functions starting with an underscore.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Allow mail(1) to look for multiple mail.rc files.
