iSCSI-SCST: A huge improvements in errors recovery and iSCSI RFC complaince as well as performance. Also: - Fixes and improvements for MaxOutstandingR2T>1 - Flow control tracing added. - Cleanups SCST core: - Now for scst_cmd_init_stage1_done() commands preprocessing_done() is always called before xmit_response(), even in case of abort or error. - Fixed recently introduced bug, which can lead to sending responses for aborted commands after reply on the corresponding TM command already sent. - Flow control tracing added. - Now it is possible to call functions setting commands execution status (e.g., scst_set_cmd_error_status()) several times for the same command. Only the first call will be completed, other calls - ignored. - All commands are counted and shown in proc/sysfs now. Before only active, i.e. not yet executed commands, were counted and shown there. git-svn-id: http://svn.code.sf.net/p/scst/svn/trunk@1431 d57e44dd-8a1f-0410-8b47-8ef2f437770f
