This reverts commit 50497292 which broke the

I don't think this change is necessary.  If I'm wrong, please recommit this
changeset with an appropriate fix for ARM.

34bb443e broke the build but in a subtle way.
The patch on the ML was actually based on the 1.1.1 stable branch
(accidentally).  When I merged it from the ML, the fuzzing got resolved in a
such a way that the newly introduced Makefile dependency on GENERATED_HEADERS
got lost (that was not in 1.1.1).

The dist bits also got duplicated (but this is just cosmetic).

All current users (IDE, SCSI and virtio-blk) happen to share this 20
characters limit.  Still, it should be left to device models.  They
already enforce their limits.  They have to, as the DriveInfo limit
only affects legacy -drive serial=..., not the qdev properties.

usb-storage, which doesn't limit serial number length, also uses
DriveInfo for -usbdevice.  But that doesn't provide access to
DriveInfo serial.

Signed-off-by: NKevin Wolf <kwolf@redhat.com>

There are two producers of these hints: drive_init() on behalf of
-drive, and hd_geometry_guess().

The only consumer of the hint is hd_geometry_guess().

The callers of hd_geometry_guess() call it only when drive_init()
didn't set the hints.  Therefore, drive_init()'s hints are never used.

Thus, hd_geometry_guess() only ever sees hints it produced itself in a
prior call.  Only the first call computes something, subsequent calls
just repeat the first call's results.  However, hd_geometry_guess() is
never called more than once: the device models don't, and the block
device is destroyed on unplug.  Thus, dropping the repeat feature
doesn't break anything now.

If a block device wasn't destroyed on unplug and could be reused with
a new device, then repeating old results would be wrong.  Thus,
dropping the repeat feature prevents future breakage.

This renders the hints unused.  Purge them from the block layer.

This isn't quite orthodox.  CHS translation is firmware configuration,
communicated via the RTC's CMOS RAM, not a property of the disk.  But
it's best to treat it just like geometry anyway.

Maintain backward compatibility exactly like for geometry: fall back
to DriveInfo's translation, set with -drive trans=...

Bonus: info qtree now shows the translation.  Except when it shows
"auto": that's resolved by pc_cmos_init_late().  To be addressed
shortly.
