6d1cbe3695 Make ioctl(FIONREAD) on the master side of a pty return the amount of
data which can be read, as expected. Before, the call fell through a
"case" statement and was forwarded to the slave side, returning the
data which can be read by the slave.
The new behaviour also matches Linux and OSF/1.

c6186face4 Welcome to 4.99.55:
- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call.  It will
  indicate which event (POLL_IN, POLL_OUT, etc) happen.  If unknown,
  zero may be used.

Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>

4e38160d4d Do not "return 1" from kqfilter for errors. That value is passed
directly to the userland caller and results in a mysterious EPERM.
Instead, return EINVAL or something else sensible depending on the
case.

f03f3b9452 Split the ptm driver out of tty_pty.c into its own file. From that split
the code that `knows' about /dev/[pt]tyXX names (the BSD ptys) into a separate
file. Make an interface to be used by the tty creating provider. The code
to enable old PTY searching via ptm is enabled via COMPAT_BSDPTY, and it
is turned on by default on all kernels that have compatibility options enabled.

cfb2dd92f0 Fix (and simplify) interaction between check_pty() and pty_maxptys().
Lock setting/clearing of tp->t_oproc to guarantee concurrent opens can't
both suceed and that code in tty.c can't get a NULL t_oproc if the value
is re-read after being checked.
There are still MP issues with pt_flags, pt_send and pt_unctl.
Maybe problems that require TTY_LOCK() to be taken before calling std tty
functions.

960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V
