[Qemu-block] [PATCH v2 0/8] More sensible default for -drive interface type

[Markus Armbruster]

Block backends defined with -drive if=T, T!=none are meant to be
picked up by machine initialization code: a suitable frontend gets
created and wired up automatically.

if=T drives not picked up that way can still be used with -device as
if they had if=none, but that's unclean and best avoided.  Unused ones
produce an "Orphaned drive without device" warning.

Many machine types default to if=ide, even though they don't actually
have an IDE controller.  A few default to if=scsi, even though they
lack a SCSI HBA.  Change their default to if=none.

While their, fix handling of index and unit for a few machines with
AHCI controllers.

With the improved default, unintentional definition of orphaned drives
should be unlikely.  Improve the "orphaned drive" warning and turn it
into an error.  Drop a few special cases of this error that are now
redundant.

v2:
* PATCH v1 6/6 dropped; if=scsi eccentricities will be addressed in a
  series of its own
* PATCH 6-8 new
