3d089cc2b5 Reintroduce the "recovered from lost interrupt" code, but in a new 
(hopefully) panic safe way.

Why the interrupts are lost is still a mystery, to me at least.

7099deadda The present defaults for the open and close for device drivers which 
provide no methods does not make any sense, and is not used by any
driver.

It is a pretty hard to come up with even a theoretical concept of
a device driver which would always fail open and close with ENODEV.

Change the defaults to be nullopen() and nullclose() which simply
does nothing.

Remove explicit initializations to these from the drivers which
already used them.

caa0284630 (atapi_cb): Reorganize error handling circuitry. 
Fix to the messages output under CAM_DEBUG_CCB: the summary sense
 information (error bits and sense key) is in the error field, not
 in the result field, of struct ata_request. No other functional change.

1ea5197e3f Disable the use of cloning use in floppy and CD drivers. 
This commit puts the relevant code snippets under #ifdef GONE_IN_5
(rather than #ifndef BURN_BRIDGES) thereby disabling the code now.

The code wil be entirely removed before 5.2 unless we find reasons
why this would be a bad idea.

c5dc1fb629 Put the device cloning functions for disk-drivers under #ifndef BURN_BRIDGES. 
For the floppy driver, use fdcontrol to manipulate density selection.

For the CD drivers, the 'a' and 'c' suffix is without actual effect and
any applications insisting on it can be satisfied with a symlink:
	ln -s /dev/cd0 /dev/cd0a

Ongoing discussion may result in these pieces of code being removed before
the 5-stable branch as opposed to after.
