From 35fa8731253a1d4dacf0c2c7d39f2b77cd4bcc0c Mon Sep 17 00:00:00 2001

Subject: Added D_TTY to the cdevswitch flags for all tty drivers.  This is
 required for the Lite2 fix for always returning EIO in dead_read().

Cleaned up the cdevswitch initializers for all tty drivers.

Removed explicit calls to ttsetwater() from all (tty) drivers.  ttsetwater()
is now called centrally for opens, not just for parameter changes.
