Received from Mark Salyzyn.
This patch adds the 'new comm' interface, which modern AAC based
adapters that are less than a year old support in the name of much
improved performance. These modern adapters support both the legacy and
the 'new comm' interfaces.

(fixed 64bit and 64G memory model, changed confusing naming convention
where fibs that go to the hardware are consistently called hw_fibs and
not just fibs like the name of the driver tracking structure)
-Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas.
