Avoid returning void

It's silly and non-conforming to standards to return void,
don't do it.

hd-geometry: Compute BIOS CHS translation in one place

Currently, it is split between hd_geometry_guess() and
pc_cmos_init_late(). Confusing. info qtree shows the result of the
former. Also confusing.

Fold the part done in pc_cmos_init_late() into hd_geometry_guess()....

Relax IDE CHS limits from 16383,16,63 to 65535,16,255

New limits straight from ATA4 6.2 Register delivered data transfer
command sector addressing.

I figure the old sector limit 63 was blindly copied from the BIOS
int 13 limit. Doesn't apply to the hardware. No idea where the old...

hw/block-common: Move BlockConf & friends from block.h

This stuff doesn't belong to block layer, and was put there only
because a better home didn't exist then. Now it does.

blockdev: Don't limit DriveInfo serial to 20 characters

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...

ide: qdev property for BIOS CHS translation

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...

ide pc: Put hard disk info into CMOS only for hard disks

In particular, don't set disk type and geometry when a CD-ROM on bus
ide.0 has media during CMOS initialization.
