Vladislav Bolkhovitin 2093dd7561 Make it possible to forcibly close SRP and FC sessions via sysfs 
That patch contains the following changes:
* Move the code for creating a "close_sess" sysfs attribute from iscsi-scst to
  the SCST core such that it becomes available for other target drivers. This
  does not change the functionality of iscsi-scst.
* Add code in ib_srpt and qla2x00t to allow a session to be forcibly closed from
  user space.

Vladislav Bolkhovitin 369863f015 Allow install SCST in any location 
Currently the install location of SCST is pretty much hard coded into 
the Makefiles to be /usr/local.

I am custom building a system for ZFS & SCST and I want to install in 
/usr instead of /usr/local.

Currently I am doing a “find . -name Makefile -exec sed -i 's:/usr/local:/usr:g'
{} \;” to accommodate this.

This patch fixes it.

Vladislav Bolkhovitin bd7c893f04 Multiple makefiles: autodetect SCST include directory 
It is cumbersome to change SCST_INC_DIR and SCST_DIR in each Makefile
before and after a release. Hence modify the Makefiles such that these
paths are detected automatically.

Vladislav Bolkhovitin 57d7bcd809 Fix 2 bugs in iscsi_attr_replace() sent by Lev Vainblat <lev@zadarastorage.com>: 
1. After attr was found in the attrs_list, it is inserted again back into the same list. As a result the list becomes corrupted.

The bug can be reproduced for example by the following sequence:

    $ echo add_attribute IncomingUser user secret111111 > /sys/kernel/scst_tgt/targets/iscsi/mgmt
    $ echo user secret222222 > /sys/kernel/scst_tgt/targets/iscsi/IncomingUser
    $ echo del_attribute IncomingUser user > /sys/kernel/scst_tgt/targets/iscsi/mgmt
    $ iscsiadm -m discovery -t st -p 127.0.0.1

Discovery fails and in syslog there is a message

    Oct  2 18:58:37 vsa-00000611 iscsi-scstd: [1059] cmnd_exec_login:940: ERROR: Authentication of initiator iqn.2011-04.com.zadarastorage:1553:vc-0 failed
