Move device name construction to a separate function.
We will reuse this function in the following commit to pass logical CHS
parameters through fw_cfg much like we currently pass bootindex.

Add logical geometry variables to BlockConf.
A user can now supply "lcyls", "lheads" & "lsecs" for any HD device
that supports CHS ("cyls", "heads", "secs").
These devices include:
* ide-hd
* scsi-hd
* virtio-blk-pci
In future commits we will use the provided LCH

Add QTest tests to check the logical geometry override option.
The tests in hd-geo-test are out of date - they only test IDE and do not
test interesting MBRs.
I added a few helper functions which will make adding more tests easier.
QTest's fw_cfg helper functions support onl

We will need to add LCHS removal logic to scsi-hd's unrealize() in the
next commit.

Add an interface to provide direct logical CHS values for boot devices.
We will use this interface in the next commits.

Relevant devices are:
* ide-hd (and ide-cd, ide-drive)
* scsi-hd (and scsi-cd, scsi-disk, scsi-block)
* virtio-blk-pci
We do not call del_boot_device_lchs() for ide-* since we don't need to -
IDE block devices do not support unplugging.

v1:
Non-standard logical geometries break under QEMU.
A virtual disk which contains an operating system which depends on
logical geometries (consistent values being reported from BIOS INT13
AH=08) will most likely break under QEMU/SeaBIOS if it has non-standard
logical geometries - for example 56

The only purpose is to already have them mapped to the correct existing
function, in case it will be used late
