[IBBUS, MTHCA, SRP] 1) (SRP) added a flow management mechanism for better sustaining the work under stress;
2) (SRP) fixed a bug of not setting max_sg value, which is used in calculating NumberOfPhysicalBreaks;
3) (SRP) added Registry parameter ModeFlags (for debugging and tuning purposes): 1 - don't use FMR_POOL, 2 - increase StorPort SG list (disallowed by DDK).
4) (SRP) fixes to support maximal buffer size (up to 1MB). It was 64KB, because of StorPort limitation of 16 SG list size.
5) (SRP) added some debug prints and statistics.
6) (IBBUS,MTHCA,SRP) added support for fmr_pool (only for kernel). Added new functions to IBAL interface, so its version increased.
7) (MTHCA) added two profile parameters to replace the values in the built-in MTHCA profile (QpNum, RdmaOutstanding).
8) (IBBUS, MTHCA) enable driver installation on Longhorn;
