cons(9): New function cn_set_tab.

Increment of progress toward eliminating bare access to cn_tab so we
can make more things MP-safe without the kernel lock (and maybe some
day better formalize console detection and switching).

cons(9): Need sys/types.h for dev_t, u_int.

Remove clause 3 (UCB advertising clause) from the University of Utah
copyright.  Confirmed by Mike Hibler, mike at cs.utah.edu - thanks!
Also, merge UCB and Utah copyright texts back into one, as they
originally were.

Extra verification by snj@.

Introduce null console. This pseudo device acts as a normal console with the
exception that it discards any output, and is useful for booting the kernel
on headless boxes.

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

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

Add cn_halt and cn_flush entries to consdevs.  (needed for dma-only console
devices).

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Catch up to -current.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Fix definitions of macros.

Commit my "devvp" changes to the thorpej-devvp branch.  This
replaces the use of dev_t in most places with a struct vnode *.

This will form the basic infrastructure for real cloning device
support (besides being architecurally cleaner -- it'll be good
to get away from using numbers to represent objects).

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

move static function getstr() to cons.c, make it publically available
as cngetsn().  there will be other consumer.

- Implement cnbell() -- ring the console bell.  The cn_bell entrypoint
  is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

Pull up to last week's -current.

Protect against multiple inclusion.

Implement poll(2).

Bring prototypes into scope.

cnputc returns void

fix definition of nullcnpollc, and add a prototype for it.

short -> int (alignment)

Properly prototype the switch table functions.  Add conf.h-like macros for
defining the switch tables.

KERNEL -> _KERNEL

don't let args default, return values, add protos

Implement cnpollc().

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

new standard, minimally intrusive ID format

Add RCS identifiers (this time on the correct side of the branch), and
incorporate recent changes in netbsd-0-9 branch.

the "struct tty *cn_tty" field in cons.c wasn't being used by anything

add rcsids to everything and clean up headers

add hp300 kernel files.  generic kernel files might need some help...
