qdev: Decouple qdev_prop_drive from DriveInfo

Make the property point to BlockDriverState, cutting out the DriveInfo
middleman. This prepares the ground for block devices that don't have
a DriveInfo.

Currently all user-defined ones have a DriveInfo, because the only way...

block: Catch attempt to attach multiple devices to a blockdev

For instance, -device scsi-disk,drive=foo -device scsi-disk,drive=foo
happily creates two SCSI disks connected to the same block device.
It's all downhill from there.

Device usb-storage deliberately attaches twice to the same blockdev,...

ide: Make it explicit that ide_create_drive() can't fail

All callers of ide_create_drive() ignore its value. Currently
harmless, because it fails only when qdev_init() fails, which fails
only when ide_drive_initfn() fails, which never fails.

Brittle. Change it to die instead of silently ignoring failure....

blockdev: Collect block device code in new blockdev.c

Anything that moves hundreds of lines out of vl.c can't be all bad.

ide: Remove redundant IDEState member conf

Commit 428c149b added IDEState member conf to let commit 0009baf1 find
the BlockConf from there. It exists only for qdev drives, created via
ide_drive_initfn(), not for drives created via ide_init2().

But for a qdev drive, we can just as well reach its IDEDevice, which...

ide: Turn drive serial into a qdev property ide-drive.serial

It needs to be a qdev property, because it belongs to the drive's
guest part.

Bonus: info qtree now shows the serial number.

not been set.

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: 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=......

Clean up test for qdev_init() failure

Some callers test for != 0, some for < 0. Normalize to < 0.
