        src/sys/arch/sparc64/dev: sab.c

        src/sys/sys: tty.h

Log Message:
As discussed on tech-kern: define a new tty internal state flag: TS_KERN_ONLY

Implement it in a few tty drivers. If this flag is set, the underlying
hardware is used by another driver and userland has no right to open
it. A few uses will appear soon in sys/dev/sun/sun{kbd,ms}.c.
