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().

into a new macro called wait_event_locked().

Micro-optimize wait_event_locked(). Switch from default_wake_function() to
autoremove_wake_function() (via DEFINE_WAIT()). The result is that
wait_queue_head_t.lock is locked once instead of twice for wakeup + wait queue
removal.

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.

- Works now if the SCST modules have been compiled into the kernel (=Y) instead of being compiled as modules (=M).
- Rename DAEMONS into SCST_DAEMONS.
- Use the same name for loading and removing the iSCSI kernel module (iscsi_scst).
- Set the path after having read /lib/lsb/init-functions instead of before.
- Remove the path from the killall command.
- When parsing /etc/default/scst, handle both parameters with and without embedded spaces correctly.

scst, iscsi-scst and qla2x00t. This makes it unnecessary hard for users to
run several target drivers simultaneously. Additionally, several variants of
these init scripts exist for different distributions. This patch unifies all
these init scripts into a single init script. Additionally, some new features
have been added:
- Kernel module parameters can now be specified per kernel module in
/etc/default/scst. An example:
ib_srpt_parameters="thread=1 srp_max_req_size=4200"
- When using the sysfs interface, compute the kernel module list from scst.conf.
Or, editing the SCST_MODULES variable is no longer necessary.
- When using the procfs interface, the SCST handler kernel module list is
computed from /etc/scst.conf. The list of target driver kernel modules must
now be configured in /etc/default/scst.
Other changes:
- scstadmin output is shown if scstadmin fails.
- Running make -C scstadmin install does no longer cause the scst script to
be started at the next reboot - it is better to leave this as an explicit step.
- Made the error message generated if the lsb-core package has not yet been
installed more clear.
- Use proper init script path on Slackware.
- make uninstall: run remove_initd under chroot if $(DESTDIR) is not empty.
- Fixed a bug in "make -C scstadmin uninstall": the path specified for removing
/etc/init.d/scst was wrong.
- The command /etc/init.d/scst restart will only try to start SCST if stopping
succeeded.
- Replaced "mkdir -m 755 -p $(DESTDIR)$(INITDIR)" by
"install -d $(DESTDIR)$(INITDIR)" because of uniformity.
These changes have been tested on Ubuntu 11.04, Fedora 15, CentOS 5.6,
Scientific Linux 6.0, openSUSE 11.4, SLES11 SP1 and Slackware 13.37.
