Open-FCoE updates (fixes and a feature) for 2.6.30 merge window

The following series implements some bug fixes to libfc and the addition of dynamic logging capabilities for libfc, libfcoe and fcoe.

The bug fixes are mostly related to the rogue rport tracking that libfc does before getting a "real" rport from the FC transport. Also there are locking and state verification fixes.

The dynamic logging code was originally mailed to linux-scsi during the 2.6.29 rc phase, but was incorrectly mixed in with fixes. This is a refresh of that patch set. Since that original patch set libfcoe and fcoe have been better distinguished as separate modules, so this patch set was modified to reflect that change.
