Sprinkle <sys/featuretest.h> where _*_SOURCE macros are consulted.

Otherwise, the feature tests might come out wrong.  For example,
header files that check for _NETBSD_SOURCE won't get the default when
no other _*_SOURCE macros are defined; header files that check for
_POSIX_C_SOURCE might miss _XOPEN_SOURCE, which is supposed to imply
a corresponding _POSIX_C_SOURCE.

PR lib/58752: various header files test _*_SOURCE macros but don't
include sys/featuretest.h

ppp: remove ioctls that never worked and crash the kernel

Remove vestigial bits of PPP HDLC support that never worked on netbsd.

The TIOCRCVFRAME ioctl was apparently intended to be called only from
within the kernel, but nothing prevents user code from calling this ioctl
and crashing the kernel.

update from HEAD

Implement tcgetwinsize() and tcsetwinsize() in libc, with access
via <termios.h> (and document them.)   Bump libc minor number for them.

Arrange for "struct winsize" to become visible in <termios.h>

Fix stty(1) so that "cols" is reported as the arg to set number of columns,
and "columns" is the alias, rather than the other way around, as "cols" is
what has been added to POSIX.

This is to conform with updates to be included in 1003.1 issue 8
(whenever that gets published) currently available at:
  http://austingroupbugs.net/view.php?id=1053   (see note 3863)
  http://austingroupbugs.net/view.php?id=1151   (see note 3856)

Welcome to NetBSD-6.99.14

In struct ptmget, used for ioctl TIOCPTMGET and TIOCPTSNAME,
increase the size of the cn and sn members from char[16]
to char[PATH_MAX].  16 chars is just not enough for reasonable things
like "/dev.amd64/pts/1234" or "/chroot/dev/pts/1234".

- 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:

merge ktrace-lwp.

The definition of IRFRAMEDISC (10) is incorrect since the value is dynamic.
The *DISC definition is only for backward compatibility with deprecated
TIOC[GS]ETD ioctls, and not needed for new TIOC[GS]LINED ioctls.
The value of IRFRAMEDISC has never been correct, so we don't have any
compatibility to be kept.
Just remove the IRFRAMEDISC defintion.

Hi Perry!

GC SUNKBDDISC & SUNMSDISC line discipline slot definitions.  Both are already
entered by ttyldisc_add() calls such that ttyldisc_add chooses the slot anyway.
Double checked by Martin.

White space nit.

Unix 98 pty multiplexor device; original code from OpenBSD.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Sync kqueue branch with -current.

Catch up to -current.

Add IRFRAMEDISC line discipline for IrDA frames.

Sync with HEAD.

Add TIOC[SG]LINED to handle symbolic line discipline names.

preliminary support for HDLCDISC [from pppd-2.3.9]

Define TIOCDCDTIMESTAMP for NTP pulse-per-second (PPS) sampling on
carrier-detect transitions, as described in the xntp documentation.
Use the same value as FreeBSD (88) for binary compatibility.
Should be implemented in lowest-level interrupt handler of serial drivers.

Import 4.4BSD-Lite for reference

Move TIOCGSID to <sys/ttycom.h>

Add flags for DTR/CTS flow control with CDTRCTS, a driver-specific
flow control flag.  Contributed by Bill Studenmund.

Nuke definitions of the unused TIOCMOD[GS] ioctls; they are pre-4.4BSD vintage
and aren't implemented in the tty(4) driver any longer.  Fixes standards/2741
(actually this is not the appropriate category) from Greg Lindahl.

Add line discipline code, initialization, and  config support for MosquitoNet's
Metricom Ricochet starmode-radio-IP driver.

New RCS ID's, take two.  they're more aesthecially pleasant, and use 'NetBSD'

new standard, minimally intrusive ID format

update to 4.4-Lite.  don't bother trying to diff.  includes local changes.
