r262957 (marcel):
Change the terminal type/class for enabled serial lines to 3wire. This
allows us to change the uart(4) driver to not hardcode specific line
settings for the serial console.
A terminal type of 3wire makes sure the console still works when no DCD
signal is present, which preserves behviour. When it is known that the
terminal server (or DCE in general) provides DCD, a terminal type/class
of std can be used. This has the effect of being logged out when one
disconnects from the console -- improving security overall.
r267591 (grehan):
Convert the potential console port over to using 3wire, for i386/amd64.
r289634:
Enable all callin ttys if the tty is an available console.

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.

Pseudo-terminals are no longer listed in this file, since the utmpx
implementation doesn't depend on ttyslot().

When we had utmp(5), we had to list all the psuedo-terminals in ttys(5)
to make ttyslot(3) function properly. Now that pututxline(3) deals with
slot allocation internally (not based on TTY names), we don't need to
list all the TTYs on the system in ttys(5) to make user accounting work
properly.
This patch removes all the entries from the /etc/ttys files, but also
the pts(4) entries that were appended implicitly, which was added in
r154838.

TEKEN_XTERM is now gone. Because we always use xterm mode now, we only
need a TEKEN_CONS25 switch to go back to cons25.

vt220 will not work better. Even though it probably will remove warnings
about unknown terminal types, a cons25 emulator is not compatible with
vt220 at all.

Even though I increased the amount of pts(4) entries in /etc/ttys some
time ago, I didn't realize back then those entries shouldn't have been
there in the first place.
I just looked at the getttyent() source code and it turns out when you
call setttyent(), it walks through /dev/pts and looks for the device
with the highest number. After you receive EOF's from getttyent(), it
makes up entries for pts(4) devices.
This means that adding entries for pts(4) is somewhat harmful, because
if you now traverse the list, you get redundant entries, so just remove
them.

As discussed with Robert Watson on the src-committers list, it is safer
to keep at least some pty(4) entries in /etc/ttys, for applications that
roll their own PTY allocation routine and only search for BSD-style
PTY's.
This means we've now just toggled the amount of entries for pts(4) and
pty(4).

Because we now use pts(4)-style PTY's exclusively, there is no use for
these entries in /etc/ttys. Right now the pts(4) entries only go from 0
to 255. Because we're going to touch these files anyway, increase the
number to 511.

The uart(4) driver has the advantage of supporting a wider variety of
hardware on a greater amount of platforms. This driver has already been
the standard on platforms such as ia64, powerpc and sparc64.
I've decided not to change anything on pc98. I'd rather let people from
the pc98 team look at this.

happen with a keyboard and monitor the console change was not as needed
in the i386 case as the Alpha case. IMO >50% of Alpha installs are using
a serial console, the change matching rev 1.7 should not be backed out.

the console reguardless of the type of console.
* Make the Alpha version match the i386 version.
