20a5f2d963 Format Portal Group Tag same as istgt does -- %4.4x instead of %x. 
SPC-4 spec tells it should be "two or more hexadecimal digits".
RFC3720 tells it is 16-bit value.

remove CTL_ISCSI_CLOSE, it wasn't used or implemented anyway.

ecba49ddfc Instead of "icltx" and "iclrx", use thread names with prefix from upper 
layer, so that one can see which side of the stack the threads are for.

6ed8f5d236 Get rid of ICL lock; use upper-layer (initiator or target) lock instead. 
This avoids extra locking in icl_pdu_queue(); the upper layer needs to call
it while holding its own lock anyway, to avoid sending PDUs out of order.

4a14441044 Update kernel inclusions of capability.h to use capsicum.h instead; some 
further refinement is required as some device drivers intended to be
portable over FreeBSD versions rely on __FreeBSD_version to decide whether
to include capability.h.
