583e969922 scsi: remove lun name
There is no need to keep a lun name anymore - we always
use the bdev name as the lun name so it is not providing any
additional value. This also keeps us from associating
the same bdev with different LUNs on different iSCSI target
nodes or vhost-scsi controllers.

Side effect of this change is:

1) Use "bdev_name" across the APIs to make it more clear
   what these names refer to.

b37d1b60f1 scsi&test/iscsi_tgt: SCSI device == iSCSI name
In the iSCSI specification, the SCSI device name is defined to be
the iSCSI name of the node.

However, when g_spdk_iscsi.nodebase is used, the SCSI device name
is made of the device specific string (the part of IQN after the
colon).

The size of the temporary buffer fullname[MAX_TMPBUF] in
spdk_iscsi_tgt_node_construct() is 1024 and the size of
spdk_scsi_dev.name is 255. The former is larger than the later.

However the max length of IQN, EUI, NAA are 223, 20, and 36,
respectively. All are less than 255.

Hence even if we use fullname as the SCSI device name, no overflow
will occur. Even if fullname is more than 255, strncpy() does not
write more than 255 in spdk_scsi_dev_construct().

It's possible to check the length of iSCSI name strictly, but I
will do the least in this patch.

e44731d659 scsi: Remove the claimed flag from LUN
Struct spdk_scsi_lun has the claimed flag as a member.

However the claimed flag is no longer required.

Moreover the claimed flag itself is not used but
spdk_scsi_lun_claim() and _unclaim() functions are used in the
UT code by hard to understand manner. Moving the logic into
spdk_scsi_lun_construct() and _destruct() in the UT code will
be more natural.

Hence remove the claimed flag from LUN and do a little refactoring
in the UT code.

eee268fea8 iscsi: Replace "ALL" by "ANY" for access control
In the accessibility control of iSCSI target, "ALL" is used to allow
ANY IP address-port pair or iSCSI name of initiators. However iSCSI
targets cannot know ALL initiators beforehand.

Hence "ANY" will be better than "ALL" and will avoid misunderstanding.

Comments and iscsi_tgt test code are also changed and UT code is added.

94e1719bf5 test/iscsi_tgt: restrict rpc ip_address test to 2 nics
This is plenty to test the add/delete IP address code.
Testing additional interfaces only adds to test time
with no additional coverage.

0404c306cb bdev: make construct RPCs return the bdev names
When creating a bdev via the RPC interface, there was no way to know
what name it was assigned (other than predicting it based on the
numbering scheme).  Change all of the relevant RPC interfaces to return
an array of bdev names so they can be used to construct LUNs/subsystems
dynamically in scripts.
