MFC r260913,266895:
Add a new flag to /etc/ttys: onifconsole. This is equivalent to "on" if the
device is an active kernel console and "off" otherwise. This is designed to
allow serial-booting x86 systems to provide a login prompt on the serial line
by default without providing one on all systems by default. Set this flag
on x86 systems for ttyu0.

# This appears to not break X11, but I'm having problems compiling the

MF22: prototype fix.

Fixed spelling of isnetworktty.

Fixed stray whitespace.

Add bitflags TTY_NETWORK/TTY_DIALUP and interface functions which
make use of them.

Allow commonly-used "insecure" as a valid keyword in /etc/ttys.
This prevents keywords after "insecure" occurs being errnoeously
parsed as comments.

Added group= facility to /etc/ttys for tty grouping for more
more manageable and convenient referencing by login.conf (login
class database) and (e.g.) login.access.

This is the first of a group of commits which implements the login
class capabilities database.

This commit was generated by cvs2svn to compensate for changes in r1539,
which included commits to RCS files with non-trunk default branches.
