The previous commit from earlier today to fix the backport of PDE_DATA was
wrong in that it would not then process the other defines for older kernels if
it detected it was running on a redhat release.

The spi master cur_transfer and cur_msg should only be changed under the
spin_lock for the master. The result is that if running user space tools, like
fxstest, that check registers on the modules, it's possible to have a message
that was not yet complete flagged as completed which would result in a bad read.
This does not affect "normal" operation of the wcaxx driver since interrupts are
not enabled during module detection, and during normal operation all access to
the resgisters is done in the context of the interrupt handler. This would only
be an issue if the interrupt handler was running and register accesses are tried
in user space context on an SMP system.

For the spans exported by the wctdm24xxp, the channels are not going to change
after they are already registered.
This eliminates a problem when analog spans are unassigned/reassigned and the
not_ready goes negative, thereby causing many warnings in the kernel.

Fixes the following warning when loading the driver:
dahdi: Warning: Span DYN/eth/eth1/00:50:c2:97:92:1d/1 didn't specify a spantype. Please fix driver!
The spantype is intended to be used by the auto configuration tools
(dahdi_genconf, pinned spans, etc..) but dynamic spans, since they are created
directly by dahdi_cfg, never take part in the pre-registration auto
configuration, therefore the span type was never used.

* This changeset adds master_span as an attribute of the span's driver:
/sys/bus/dahdi_spans/drivers/generic_lowlevel/master_span
* This is mainly used for debugging.
* Reading from it the master span number (or 0 if there is no master
span).
* Writing a number to it, force specified span to be master
* Existing Alternatives:
- grep "MASTER" from /proc/dahdi/*
- cat /sys/bus/dahdi_spans/devices/span-*/is_sync_master

If the driver is loaded with vpmsupport=0, then it was possible to create a
deadlock situation since the call into __dahdi_ec_chunk might then try to grab
the channel lock while already holding the reglock.
The purpose of grabbing reglock in the DMA routines was to protect the channel
array, which can be changed when linemode is changing. So instead, we'll
completely mask off that interrupt line from all CPUs when potentially changing
the channel array.

The octasic library is relatively large and is currently separately linked into
both the wcte13xp and wct4xxp libraries. This change moves it out into a
separate loadable module.
The bigest change from the drivers perspectives is that they must provide a
table of callbacks instead of using statically linked Oct6100UserXxxxx functions
to allow the library to communicate with actual parts on the cards.

dahdi_genconf currently does not take into account the number of spans
configured for a particular board. Therefore if you have two dual span cards
installed in the system, it could be possible to have something like this in
/etc/dahdi/system.conf:
spans=1,1,...
spans=2,2,...
spans=3,3,...
spans=4,4,...
When what you really want is something like this:
spans=1,1,...
spans=2,2,...
spans=3,1,...
spans=4,2,...
Otherwise, spans 3 and 4 will be configured to not recover the clock from the
span which is most likely NOT what you want.
