The current ibmvstgt and libsrp kernel modules are based on the tgt
infrastructure. Both modules need the scsi_tgt kernel module and the tgtd user
space process in order to function properly. This patch modifies the ibmvstgt
and the libsrp kernel modules such that both use the SCST storage target
framework instead of tgt. Porting ibmvstgt to SCST is required for upstream
acceptance of SCST.

This patch introduces one backwards-incompatible change, namely that the path
of the ibmvstgt sysfs attributes is modified. This change is unavoidable
because this patch dissociates ibmvstgt target instances from a SCSI host
instance.
because this patch dissociates ibmvstgt SRP sessions from a SCSI host instance.
Notes:
- ibmvstgt is the only user of libsrp.
- A 2.6.35 kernel tree with this patch applied does compile cleanly, the patch
itself is checkpatch clean and does not introduce any new sparse warnings.
This patch has not been tested in any other way however. The primary purpose
of this patch is to invite feedback about the chosen approach.
