Functions that dump the state of SCSI commands and task management functions
should occur in the SCST core instead of in target drivers. If anyone needs
this functionality it should be moved into the SCST core.

There is no need for a detect() method - code that is present in such
a method can be moved to module_init(). Hence declare this method
obsolete. Leave the detect pointer member in the target template for
now for out-of-tree SCST drivers.

Retry sending XFER_RDY, data and response frames if the network
driver reports that sending failed (-ENOMEM) instead of reporting
a kernel warning (WARN_ON(1)). If sending XFER_RDY or data frames
failed for another reason, report this to the initiator as a
write error (ASC = 03; ASCQ = 00 which stands for PERIPHERAL
DEVICE WRITE FAULT). If sending a response frame failed with
another error code than -ENOMEM, do not send a response.

The biggest difference is that libfc no longer allocates a sequence
and exchange for incoming requests, and that eliminates a parameter
on the receive function. This was done to help performance and
might help on short reads sometime in the future.
This also fixes an error in ft_send_read_data() that exceeds the
skb's SG list length limit on long reads when the NIC
supports large send offload.
I also made other minor changes like adding debugging.

Add a method for template get_initiator_port_transport_id()
to allow persistent reservations to work.
Initialize struct ft_sess more fully before scst_register_session()
so that ft_get_transport_id() can use it.

The target template max_hw_pending_time was zero, causing
premature timeouts and a fast retry in scst_hw_pending_work_fn().
Set it to 20 seconds, like qla2x00t does, for now.
It could be the wrong thing for tape, but should be
plenty long enough for disks.

that accepts FCP requests from libfc HBAs running Fibre Channel
over Ethernet (FCoE) and passes them to SCST.
