SCSI: BusLogic update 

From: Bob Doyle <doyle@primenet.com>

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).

to achieve the full performance that BusLogic SCSI Host Adapters and modern
SCSI peripherals are capable of, and to provide a highly robust driver that can
be depended upon for high performance mission critical applications. All of
the major performance and error recovery features can be configured from the
Linux kernel command line or at module initialization time, allowing individual
installations to tune driver performance and error recovery to their particular
needs.

The BusLogic Driver Error Recovery Option allows for explicitly specifying
the Error Recovery action to be performed when BusLogic_ResetCommand is
called due to a SCSI Command failing to complete successfully. The following
options are available:
ErrorRecovery:Default
The "ErrorRecovery:Default" or "ER:Default" option selects between the Hard
Reset and Bus Device Reset options based on the recommendation of the SCSI
Subsystem.
ErrorRecovery:HardReset
The "ErrorRecovery:HardReset" or "ER:HardReset" option will initiate a Host
Adapter Hard Reset which also causes a SCSI Bus Reset.
ErrorRecovery:BusDeviceReset
The "ErrorRecovery:BusDeviceReset" or "ER:BusDeviceReset" option will send
a Bus Device Reset message to the individual Target Device causing the
error. If Error Recovery is again initiated for this Target Device and no
SCSI Command to this Target Device has completed successfully since the Bus
Device Reset message was sent, then a Hard Reset will be attempted.
ErrorRecovery:None
The "ErrorRecovery:None" or "ER:None" option suppresses Error Recovery.
This option should only be selected if a SCSI Bus Reset or Bus Device Reset
will cause the Target Device or a critical operation to suffer a complete
and unrecoverable failure.
ErrorRecovery:<Target-Spec>
The "ErrorRecovery:<Target-Spec>" or "ER:<Target-Spec>" option controls
Error Recovery individually for each Target Device. <Target-Spec> is a
sequence of "D", "H", "B", and "N" characters. "D" selects Default, "H"
selects Hard Reset, "B" selects Bus Device Reset, and "N" selects None.
The first character refers to Target Device 0, the second to Target Device
1, and so on; if the sequence of "D", "H", "B", and "N" characters does not
cover all the possible Target Devices, unspecified characters are assumed
to be "D".
