scstadmin: Multiple -write_config bug fixes.
...
Bug fixes:
- Do not write out the line "# Non-key attributes" for the top level if -nonkey
has not been specified.
- If -nonkey has been specified, write out the device handler creation time
attributes too (blocksize, o_direct, read_only, removable, ...).
- If -nonkey has been specified, write out the LUN creation time attributes
too (read_only).
Also, simplify the -write_config implementation by introducing the Perl
subroutines serializeKeyAttr() and serializeNkAttr().

With NPIV initiators being destroyed and recreated, the loop_id and/or
...
the d_id of a virtual initiator may change. The current implementation not
always catches these changes, which leads to wrong virtual devices
being presented to the initiators. This can lead to i.e. corruption of LUN
content and multiple initiators writing to the same LUN, although the
LUN's access group only contains a single port.
Until a better solution is found, we schedule a session deletion for the
nexus when receiving an ELS port logout message. That way SCST
will re-initialize both loop_id and d_id when the initiator reconnects
before the actual deletion takes place. The performance impact is
minimal (few milliseconds) and currently necessary.
