The ->init() callback can be used for calling ether_setup() in case
of encapsulation "ISDN over ethernet", for the other cases it does not
make sense anyway.

X25 needs notification when encapsulation is set to X25 and when
it is changed to something else again, so let's have some callbacks
for init/cleanup.

Use a struct of methods and parameters to describe the
different kinds of network interfaces supported by isdn_net.c
and friends.

PPP wants callbacks at the time a connection between ISDN channel
and network interface is established, i.e. before dialing to
avoid dialing when no ipppd is present, so use generic
bind/unbind callbacks.

The method to find out if an incoming call is addressed to
any of the ISDN network interfaces is horrible. A bit of splitting
and dropping the swap channels if exclusive logic makes it a bit
better at least.

The same information is present as (->isdn_slot >= 0), so don't
duplicate it (and risk it getting out of sync)

No need to duplicate that function privately.

When using exclusive mode, we already reserved our channel
at the time that mode was set, so no need to get a free channel
in this case.

Also, indent cleanups to isdn_net_start_xmit().

We will need the index of the channel we reserved later, so override
the meaning of ->exclusive.

Put the test for lp->flags & ISDN_NET_CONNECTED into an inline
function called isdn_net_bound(), which more accurately names what
we are testing for, i.e. the interface being bound to a hardware
ISDN channel, which however is not necessarily online yet.

Again, instead of a switch statement, just use a callback.

Use the same form for the already existing PPP / X.25 receive functions
as for all the other ones, + small fixes.

Break syncPPP and UI HDLC specific parts out of isdn_net_header()
and move it to more appropriate places.

Break the CISCO specific part out of the generic isdn_net_header()
and move it to the CISCO code.

isdn_net handles all kind of interfaces, e.g. raw IP, ethernet over ISDN,
PPP - this is a cleanup making the setup of a net_device specific to the
type of interface.

Again, instead of having stuff cluttered all over isdn_net.c, put
it into the files where it belongs and get rid of the 
#ifdef CONFIG_ISDN_X25 / CONFIG_ISDN_PPP by using dummy stubs if
necessary.

Same thing for CONFIG_ISDN_PPP.

SyncPPP and X25 are already (kind of) separated, so do the same for CISCO
HDLCK.

Try to convert the setup of network interfaces into something readable.
In particular, use dummy inline functions to get rid of
#ifdef CONFIG_ISDN_* spread all over the place everywhere and separate 
stuff into smaller functions.
