[PATCH] Sync up ieee-1394

Lots of this patch is trivial code cleanups (static vars were being
intialized to 0, etc).

There's also some fixes for ISO transmits (max buffer handling).
Aswell, we have a few fixes to disable IRM capabilites correctly.  We've
also disabled, by default some generally unused EXPORT symbols for the
sake of cleanliness in the kernel.  However, instead of removing them
completely, we felt it necessary to have a config option that allowed
them to be enabled for the many projects outside of the main kernel tree
that use our API for driver development.

The primary reason for this patch is to revert a MODE6->MODE10 RBC
conversion patch from the SCSI maintainers.  The new conversions handled
directly in the scsi layer do not seem to work for SBP2.  This patch
reverts to our old working code so that users can enjoy using Firewire
disks and dvd drives again.

We are working with the SCSI maintainers to resolve this issue outside
of the main kernel tree.  We'll merge the patch once the SCSI layer's
handling of the MODE10 conversion is working for us.
