Rearrange block headers
Changing block.h or blockdev.h resulted in recompiling most objects.
Move DriveInfo typedef and BlockInterfaceType enum definitionsto qemu-common.h and rearrange blockdev.h use to decrease churn.

ide: Improve error messages
Use error_report(), because it points to the error location.
Reword "tried to assign twice" messages to make it clear that we'recomplaining about the unit property.
Report invalid unit property instead of failing silently....
ide: Make ide_init_drive() return success
It still always succeeds. The next commits will add failures.

qdev: Decouple qdev_prop_drive from DriveInfo
Make the property point to BlockDriverState, cutting out the DriveInfomiddleman. This prepares the ground for block devices that don't havea 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=foohappily 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,...
pc: Fix CMOS info for drives defined with -device
Drives defined with drive if=ide get get created along with the IDEcontroller, inside machine>init(). That's before cmos_init().Drives defined with -device get created during generic device init.That's after cmos_init(). Because of that, CMOS has no information on...
ide: Make it explicit that ide_create_drive() can't fail
All callers of ide_create_drive() ignore its value. Currentlyharmless, because it fails only when qdev_init() fails, which failsonly 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 findthe BlockConf from there. It exists only for qdev drives, created viaide_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'sguest part.
Bonus: info qtree now shows the serial number.
ide: Fix info qtree for ide-drive.ver
Show the actual default value instead of <null> when the property hasnot been set.
block: add topology qdev properties
Add three new qdev properties to export block topology information tothe guest. This is needed to get optimal I/O alignment for RAID arraysor 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 tospecify the version which the virtual disk/cdrom should report to theguest. 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.
