Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.
