6b7e9d0af2 Lib/iSCSI: add the LUN Resize support
From SAM-4, section 5.13 (Sense Data);
“When a command terminates with a CHECK CONDITION status, sense data shall be returned
in the same I_T_L_Q nexus transaction (see 3.1.50) as the CHECK CONDITION status. After
the sense data is returned, it shall be cleared except when it is associated with a unit
attention condition and the UA_INTLCK_CTRL field in the Control mode page (see SPC-4)
contains 10b or 11b.”

SPDK does not set UA_INTLCK_CTRL to 10b or 11b, so we set the unit attention condition
immediately against a single IO or Admin IO after reporting it via a CHECK CONDITION.
Once the failed IO received at iSCSI initiator side, it will be retried. In the case of
resize operation, if there is no IO from iSCSI initiator side, the unit attention
condition will be delayed to report until the first IO is received at the iSCSI target
side.

Meanwhile, we clear the resizing (newly added) flag on our SCSI LUN structure after
first time we report the resize unit attention condition.

The kernel initiator won’t actually resize the corresponding block device automatically.
It will report a uevent, and then you can set up udev rules to trigger a rescan. SPDK
iSCSI initiator will automatically report the LUN size change.

6751909838 bdev/iscsi: unregister conn poller when idle
There's no need to keep polling with iscsi_bdev_conn_poll() when the request
list is empty, as new requests already restart the poller when needed.

b885e23b95 bdev/iscsi: apply max_unmap and max_unmap_segments to bdev layer
The bdev layer can do the unmap split now based on the backend
device.  For now we only use 1 unmap descriptor, the bdev layer
can help us to do the split.

Fix issue #1888

6cebe9d06b nvmf: Support physical block size if exposed by bdev
(Note: this patch was previously applied as b32cfc46 and then reverted
as 63642bef.)

Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K

iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16

NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.

This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.

Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

Fixes #1884
