CVS commit: src/sys

["Christos Zoulas" <christos%netbsd.org@localhost>]

Module Name:    src
Committed By:   christos
Date:           Sat Sep 24 00:05:39 UTC 2011

Modified Files:
        src/sys/kern: tty.c tty_subr.c
        src/sys/sys: tty.h ttycom.h

Log Message:
- Introduce a sysctl to control the default tty queue size kern.tty.qsize,
  which defaults to 1024 as before.
- Add two ioctls TIOC{G,S}QSIZE to read and adjust the queue size on
  individual ptys.

NB: ttys (and ptys) still silently (or beepingly (IMAXBEL)) drop
    characters if the queue size is exceeded. I.e. you can appear
    to succeed writing to the {p,t}ty, but not all characters will
    have made it if the queue overflows.  CVS:
