is being renamed to macppc. This is to allow sharing of common code
between different powerpc base platforms.

bit flags ORed together.  Currently the only flags defined are
_PASSWORD_SECUREONLY and _PASSWORD_OMITV7 but this is enough to
cause pw_mkdb() to run pwd_mkdb with the options we want.
With this change we no longer generate the old V7 passwd file when
only the extra fields in master.passwd (or the encrypted password)
have changed.  There are other programs that could probably use
the _PASSWORD_OMITV7 flag; they will be converted at a future date.

Make '/etc/remote' a working example, with some lengthy comments that
might help people trying to use it.
Remove untruths and beef up documentation for tip(1), remote(5) and
phones(5). In particular remove last reference to the 'cu' tip
interface since we use the 'cu' that comes with uucp, improve
documentation on phone numbers and flesh out documentation on
acu/modems supported. Document PHONES and REMOTE environment
variables.
Cleanup parsing of /etc/phones (so our example can be used) and ignore
lines with empty phone numbers instead of aborting the scan of the
file. This makes /etc/phones parsing consistant with ':pn:' capability
parsing. Don't try to dial empty phone numbers in either case.
