f00200d8a4 Preparation commit for the tty cleanups that will follow in the near
future:

rename ttyopen() -> tty_open() and ttyclose() -> tty_close().

We need the ttyopen() and ttyclose() for the new generic cdevsw
functions for tty devices in order to have consistent naming.

0567d4ef5f Pick the hotchar out of the tty structure instead of caching private
copies.

No current line disciplines have a dynamically changing hotchar, and
expecting to receive anything sensible during a change in ldisc is
insane so no locking of the hotchar field is necessary.

17b52df3d7 Centralize the line discipline optimization determination in a function
called ttyldoptim().

Use this function from all the relevant drivers.

I belive no drivers finger linesw[] directly anymore, paving the way for

LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

dc2e474f79 Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

5596676e6c KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

3176716b49 Always leave SP_DCEN on (monitor DCD). Otherwise the firmware *really*
does ignore DCD.  Even TIOCMGET cannot read DCD as the firmware doesn't
report it.  This has pretty interesting effects for ppp(8) which runs
in clocal mode and polls carrier (!).  (Specialix's linux driver does
this too)

Also update the firmware to 3.0.6 for the SX cards, as apparently there
was a problem with floating (disconnected) DCD pins causing stray carrier
transitions, especially at port open time.

It seems to work here, and carrier loss is detected nearly immediately
rather than having to wait for a LQR timeout (a few minutes) before ppp(8)
gives up.

a2c68c62db This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll

663cbe4fc2 Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().
