devices).

e0cc03a09b merge kqueue branch into -current 
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

77a6b82b27 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.

5fa952b83f As in PR kern/10999 from Matthew Orgass, make the panic message more 
helpful in the case where no console device has registered.

07677cc805 Use back the 'u'&037 form - since it's CTRL-u, it's more readable that way 
Use \007 instead of symbolic constant, since that's what is more often used.

a183d34f04 - Implement cnbell() -- ring the console bell. The cn_bell entrypoint 
is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

34ac381d05 don't cdevvp() if a vnode for the dev already exists. Note that that's 
conceptually icky; you end up ref'ing a 'real' vnode, and hence perhaps
tying down a file system; should be able to reference a 'fake' one,
but i doesn't appear save to cdevvp() if vnode for same dev is already
around...  also, mark vfinddev()s XXX (for later).

1eacd36710 pccons.c now dynamically allocates it's "struct tty" 
cons.c's "struct tty *cn_tty" wasn't used by any of the kernel, and goes away.

general prototypes.  Casts where necessary.

0b12df586d 1. It is now possible to build a kernel that does not have a pc0 device driver. 
2. "press any key to reboot" reads the key from the console.
3. wddump() still needs a non-blocking getc() routine (or flush)
