move all ttyE* entries that use "vt100" emulation to wsvt25 term type.
The terminfo vt220 entry lacked (correctly) a delete key entry, which
was a regression against the netbsd-5 termcap entry. On the other hand,
only a very small number of foreign systems lacks support for wsvt25
nowadays.
as the console. Now when coming up in single user mode the tset in
/.profile can set the terminal type correctly.
Note: I believe constty should be 'on' and console 'off', but thats a
separate discussion
boot console tty, so that the console is on the same place that the kernel
dmesg output goes, whether wscons or serial. Users who want to use tty00
or ttyE0 explicitly can change /etc/ttys themselves.
Also use "vt100" as terminal type for /dev/console (for a reasonable baseline
that also works with wscons; pccons is long since no longer default).
This addresses PR install/13249, i386-specific, but may be appropriate to
apply to all ports.
