fe9781bb78 Make sequence numbers checks more strict.
While we don't support MCS, hole in received sequence numbers may mean
only PDU loss.  While we don't support lost PDU recovery, terminate the
connection to avoid stuck commands.

While there, improve handling of sequence numbers wrap after 2^32 PDUs.

2efae2e6b1 For both iSCSI initiator and target increase socket buffer sizes before
establishing connection.

This is a workaround for Chelsio TOE driver, that does not update socket
buffer size in hardware after connection established, and unless that is
done beforehand, kernel code will stuck, attempting to send/receive full
PDU at once.

69cdfe7aaa In conf_apply() remove iSCSI ports from kernel before removing LUNs.
Previous order confused initiators with messages about "removed" LUNs
during simple ctld restart without any real config change.  After this
commit initiators only reestablish lost connection, receive "Power on
occurred" UNIT ATTENTION status and continue normal operation.

4fd3a4b49d Make both iSCSI initiator and target support base64 encoded CHAP data.
While all tested initiators and targets use hex-encoded CHAP data, RFC also
allows base64 encoding there, and Microsoft certificaition tool uses it.

962052e82a Remove the distinction between strings and numbers from ctld(8) yacc parser.
This fixes problems with passing strings that look like numbers to clauses
that expect strings; previously it caused syntax errors and had to be worked
by user, using quotes.  The workaround introduced in r267833 is no longer
neccessary.

b91222fa4f Add basic iSNS client to the iSCSI target.
This makes ctld(8) register its iSCSI targets and portals on configured
iSNS servers to allow initiators find them without active discovery.

Fetching of allowed initiators from iSNS is not implemented now, so target
ACLs still should be configured manually.
