amiga/msc(4): Convert to ttylock/ttyunlock.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found

cdevsw/bdevsw entries so even if so I think we come out ahead.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

CFATTACH_DECL_NEW, device_t, cfdata_t

Rename ttymalloc() to tty_alloc(), and ttyfree() to tty_free() for
consistency. Remove some unnecessary malloc.h inclusions as well.

For some reason the 6502 clock detection routine takes 1553 iterations
of the delay loop to finish on a normally clocked A2232.

Properly fix the "hanging in tty" bug that was worked around with cv_wakeup()
some time again.

- Factor out too many copies of the same bit of tty code.
- Fix another tty signalling/wakeup problem.

Merge tty changes from the vmlocking branch.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

TRUE -> true, FALSE -> false

Adapt to KAUTH_DEVICE_TTY_PRIVSET and KAUTH_DEVICE_TTY_OPEN.

Adapt MD code to KAUTH_DEVICE_TTY_OPEN. Patch from Matt Fleming, thanks!

Use the LWP cached credentials where sane.

Use device_unit().

Change the driver open function's conditional for overriding exclusive tty
use from checking the proc's uid to suser(9), and account for the use of
privileges. Noted by David Holland in PR kern/3112

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
