BusLogic update - take 2

[Bob Doyle <doyle@primenet.com>]

This is my second pass through the BusLogic SCSI driver.  It
incorporates some comments received on the first version.

This patch is against linux-2.6.1.  It works for me but the normal
caveats apply.

Please retrieve (~150kb) from:

<http://home.globalcrossing.net/~doyle/buslogic.patch>

Deleted dead code:
- BusLogic_ReportTargetDeviceInfo()
- BusLogic_SelectQueueDepths()
- BusLogic_SendBusDeviceReset()
- BusLogic_ResetCommand()

Fixed:
- removed dependency on "scsi_obsolete.h"
  o Changes to BusLogic_ResetHostAdapter()
  o Changes to BusLogic_AbortCommand()
- removed the gratuitous typedefs per Christoph's comments
- several functions with incorrect __init and __exit sections.
- Removed vestiges of the 'Error Recovery' command line function (which
  is fundamentally incompatible with the new EH design).

Left to do:
- Test eh_abort_handler
- Test eh_host_reset_handler
- Test as module
- Straighten out FlashPoint conditional compile so it doesn't
  require #include "FlashPoint.c". 
- Please ignore the long line length and the very lengthy
  identifiers (for now).

Bob.
