block: add topology qdev properties

Add three new qdev properties to export block topology information to
the guest. This is needed to get optimal I/O alignment for RAID arrays
or SSDs.

The options are:

- physical_block_size to specify the physical block size of the device,...

ide save/restore current transfer fields

If migration takes place between write of the bmdma address register and
write of the command register (to initiate DMA), the destination will
not properly start the DMA op, hanging the guest:

ide: device version property

This patch adds a new property named 'ver' to ide-drive which allows to
specify the version which the virtual disk/cdrom should report to the
guest. By default this is the qemu version (i.e. 0.12). usage:

-drive if=none,id=disk,file=......

workaround for cmd646 bmdma register access while no dma is active

This is a workaround only, and is a partial revert
of a few changes to BMDMAState which removed pci_dev
field on the way.

- cmd646 pci_from_bm() expects bm->unit value to
correspond with bm data being passed to callback...

qdev: Replace device names containing whitespace

Device names with whitespace require quoting in the shell and in the
monitor. Some of the offenders are also overly long. Some have a
more convenient alias, some don't.

The place for verbose device names is DeviceInfo member desc. The...
