MFC r262957, r267591, r289634:

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.

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.

Remove the reference to pseudo-terminals from the description.

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

Remove pseudo-terminals from ttys(5).

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.

Switch the default terminal emulation style to xterm for most platforms.

Right now syscons(4) uses a cons25-style terminal emulator. The
disadvantages of that are:

- Little compatibility with embedded devices with serial interfaces.
- Bad bandwidth efficiency, mainly because of the lack of scrolling
regions.
- A very hard transition path to support for modern character sets like
UTF-8.

Our terminal emulation library, libteken, has been supporting
xterm-style terminal emulation for months, so flip the switch and make
everyone use an xterm-style console driver.

I still have to enable this on i386. Right now pc98 and i386 share the
same /etc/ttys file. I'm not going to switch pc98, because it uses its
own Kanji-capable cons25 emulator.

IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):

- Run the application inside script(1), try to reduce the problem and
send me the log file.
- In the mean time, you can run `vidcontrol -T cons25' and `export
TERM=cons25' so you can run applications the same way you did before.
You can also build your kernel with `options TEKEN_CONS25' to make all
virtual terminals use the cons25 emulator by default.

Discussed on: current@

Remove the note about using vt220, which makes no sense at all.

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.

Remove pts(4) entries from /etc/ttys.

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.

Restore 256 pty(4) entries.

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).

Requested by: rwatson

Remove old BSD-style entries from /etc/ttys and increase pts(4) to 512.

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.

Discussed with: philip (ex-mentor)

Make uart(4) the default serial port driver on i386 and amd64.

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.

Approved by: philip (mentor), marcel

Bump up the number of ttys supported by pty(4) to 512 by making use of

Mention that terminal type vt220 will work better if one needs
interoperability with other systems like Solaris or GNU/Linux.

Revert to rev 1.6 until post 4.0-R. As probably 98% of i386 installs
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.

* Use `console' rather than `ttyv0' so there will always be a getty on
the console reguardless of the type of console.
* Make the Alpha version match the i386 version.
