TAB/spaces/indents cleanup.

Make local devsw functions static.

No visible regression on TT030.

fix various typos in comments, messages and documentation.

include "ioconf.h" to get the 'void <driver>attach(int count);' prototype.

branches: 1.34.4;
Add d_discard to all struct cdevsw instances I could find.

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

branches: 1.33.2;
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 and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Remove extra whitespace added by a dumb tool which replaced bcopy with memcpy.

bcopy -> memcpy

Ansify function definitions w/o arguments. Generated with sed.

ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

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

replace the somewhat strange poll routine with standard nopoll() (a.k.a
seltrue())

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.

branches: 1.18.4;
Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.

branches: 1.17.4; 1.17.8;
Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

branches: 1.16.8; 1.16.18;
Changed grf mmap that it is closer to XFree. VGA memory on et4000/et6000
is now at offset 0xa0000.

- Provide the reasonable size that can/may be mmap-ed. This might differ
from the current frame buffer size.
- The et-driver now allows for a 16Kb io-region (was 8Kb) that can be
mapped. The XFree server uses this.

Allow the control registers to be mapped too.

backout previous kprintf changes

printf -> kprintf, sprintf -> ksprintf

Checkpointing my et4000 work. Note that the et-console will not be
functional until the minimal pci-support is checked in.

Catchup with -current:
- Extra argument to boot()
- select -> poll

Prepare for (soon to come) et4000 PCI console.

Yet more prototyping and -Wall fixes.

First bunch of changes due to stricter prototype checking.

Remove 2 wrong proto-types.

Remove the pointer to view_t from the grf-structure, use viewview(dev)
to obtain the pointer instead. This removes a kernel-crash that happened
when something was written to the console while the console was being
resized.

ite_newsize(): Do not reallocate a display when the actual display mode
will be the same. Fixes a nasty bug where ite0 and ite1 share the same
bitmap.

map --> mmap

Make ite ioctl work and fixup the colormap stuff.
