jdolecek 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

gehenna 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.

martin 2fe85a6623 Uniformly pass a "struct isdn_l3_driver *" through layer 2, so we
do not have to search for that driver later while we already knew it
at layer 1.

martin 0bc69b6498 Now that we have all the pieces of the puzzle available start to unriddle
and move them in their proper places.

Move the BRI registry from layer 2 (duh!) to layer 4, so active cards
(which don't have layer 3 or layer 2 in their driver). Remove all remaining
hard coded controller and driver types. Remove any arbitrary hard coded
limits, at least those that show up in the internal API.

This fixes PR 15950.

martin 4a7710e8d9 Fix a long standing confusion between n_mgm_command and mph_command_req
by removing the former completely.
This makes isdntrace work again.

martin 94881fb123 Rename ISDN devices, per discussion on tech-kern. The network devices
become ippp (ISDN ppp) and irip (ISDN raw IP). The character device now
are called: /dev/isdn (isdnd <-> kernel communication), /dev/isdnctl (dialing
and other control), /dev/isdntrc* (tracing), /dev/isdnbchan* (raw B channel
access, i.e. for user land PPP) and /dev/isdntel* (telephone devices, i.e.
for answering machines).

martin 83930a016c Demangle an #ifdef mess and make all ioctl routines take an u_long
as the command argument. Before we were subject to subtle sign extension
differences depending on char being signed or unsigned.

martin 5171d409a5 First step to cleanup the hardware driver <-> upper layers interface.
This now provides slightly more functionality than the FreeBSD layer1-newbus
interface. It was meant to be a simple change to one header and a few
c files, but the change rippled all through various stuff.

To prevent a change to the kernel<->userland interface right now the kernel
is now lying about card types to userland (but who cares). This will be fixed
when the userland interface changes, after layer 3 <-> layer 4 has been
fixed.

Functional changes:

Provide a clean interface for hardware drivers to attach to the upper
layers. This will need another small change in the B-channel handling
when a similar change to the layer 3 <-> layer 4 interface happens.

Avoid passing indices into global arrays of pointers around, instead pass
the pointers itself. Don't code hardware driver types by predefined magic
numbers (think LKM). Prepare for detachable drivers (think pcmcia).

While there remove some sets of function pointers always pointing to the
same function (meant to be the configurable set of D channel protocol
handlers). It is unlikely another supported D-channel protocol will fit into
that (maximal layer interface) abstraction. When we get support for another
protocol, we will need to come up with a workable interface. Besides, the
old implementation was, uhm, strange.

martin 6b82e7fe42 64bit police.
Rumors say there are archs without ISA busses, so avoid including
(uneccesarily) isa bus headers in MI files.
XXX this is the minimal solution, layer interface calls will have
XXX to be revisited later
