f3732fd15b Second half of the dev_t cleanup.
The big lines are:
	NODEV -> NULL
	NOUDEV -> NODEV
	udev_t -> dev_t
	udev2dev() -> findcdev()

Various minor adjustments including handling of userland access to kernel
space struct cdev etc.

c5c09c282b - Remove the __FBSDID and put the $FreeBSD$ tag in the comment above,
so that including this file more than once works.
- Fix some style bugs while I'm here.

dc08ffec87 Device megapatch 4/6:
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

b01a62069f Correct usage of mtx_init() API. This is not a functional change since
the code happened to work because MTX_DEF and NULL are both defined as 0.

c46def32e2 Add a generic LED driver for flashing lamps.
The hardware driver decides the name under /dev/led and provides
the function to turn the lamp on/off.

All leds are serviced by a single timeout which runs at a basic rate
of hz/10.

The LED is controlled by ascii strings as follows.

0	Turn off.
1	Turn on.
f	Flash: _-
f2	Flash: __--
f3	Flash: ___---
f4...f9 etc.
d%d	Digits.  "d12": -__________-_-______________________________
s%s	String, roll your own:
	'a-j' gives on for (1...10)/10 sec.
	'A-J' gives on for (1...10)/10 sec.
	'sAaAbBa': _-_--__-
m%s	Morse
	'.' dot
	'-' dash
	' ' letter space
	'\n' word space

My mdoc skills do not reach to express that.
