The bunch of pending changes. Sorry, it's quite big.

- "RECEIVE DIAGNOSTIC RESULTS" command handling fixed
 - Obtaining device queue parameters in scst_obtain_device_parameters() changed to handle NOT READY sense
 - Fixed possible dev_cmd_count underflow
 - Minor iSCSI-SCST connection closing cleanups and fixes
 - Semantic of other *_atomic flags changed a bit. Now they are intended only to allow SCST to optimize execution context. The corresponing functions now can *always* be called on atomic context and, if necessary, should manually determine that using scst_cmd_atomic() function and restart using corresponding *_NEED_THREAD_* return value.
 - scst_cmd_get_tgt_resp_flags() and SCST_TSC_FLAG_STATUS flag made obsolete and replaced by scst_cmd_get_is_send_status(). All in-tree drivers updated accordingly
 - Cleanup: preprocessing_done_atomic removed, now preprocessing_done() callback always called on thread context
 - 64-bit cleanups
 - Documented that iscsi-scst-adm is currently broken and explained why
 - In user space Makefile's added possibility to specify external linker flags
 - Minor performance optimizations
 - Other minor cleanups
