Vladislav Bolkhovitin 7eddeb82ab - Some iSCSI performance fixes 
- __attribute__((aligned(sizeof(long))) added to all field with different protection than the previous field to make sure they don't share the same bus line. Just in case, actually, compiler should do the alignment by default.

 - Small docs updates.

Vladislav Bolkhovitin 05d1bbfedc A huge chunk of related to each other changes, which had to be tested together. 
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.
