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 e14f4779db Avoid duplicate expensive lookups by passing a pointer to the call
descriptor/a pointer to the layer 3 state directly to driver functions,
instead of their ID/index.

martin f5e2c967fc Split BRI attaching into two phases, so lower layer drivers can get their
BRI identifier and L3 driver state early on, then finish initializing and
announce the controller to userland when it's ready.

martin ea03e4fc22 Better check ioctl parameters and reject requests for not (currently)
present controllers.

Clear our TEI on persistent (physical) deactivation, instead of setting it
to a bogus 0.

martin 0db68b667b Now that we have all pieces in place (and enough granularity to specify
B-channel and D-channel drivers separately) split the Fritz!PCI card
driver out of the isic driver.

The new device is called "ifpci" and uses the same D-channel driver as the
isic devices, but has it's own B-channel driver.

martin a994533d0a Make pcmcia cards detach properly.
Notify userland of attaching/detaching cards.
This partly fixes PR 15951.

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 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
