ide: Replace IDEState members is_cdrom, is_cf by drive_kind
The two aren't independent variables. Make that obvious.

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: Fix virtual media change for if=none
BlockDriverState member removable controls whether virtual mediachange (monitor commands change, eject) is allowed. It is set whenthe "type hint" is BDRV_TYPE_CDROM or BDRV_TYPE_FLOPPY.
The type hint is only set by drive_init(). It sets BDRV_TYPE_FLOPPY...
block: Move error actions from DriveInfo to BlockDriverState
That's where they belong semantically (block device host part), eventhough the actions are actually executed by guest device code.
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: Split ide_init1() off ide_init2()
ide: Change ide_init_drive() to require valid dinfo argument
IDEState members drive_serial_str and version are now left empty untilan actual drive is connected. Before, they got a default value thatwas overwritten when a drive got connected. Doesn't matter, because...
ide: Split non-qdev code off ide_init2()
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 ide_dma_cancel
When cancelling a request, bdrv_aio_cancel may decide that it waits forcompletion of a request rather than for cancellation. IDE therefore can'tabandon its DMA status before calling bdrv_aio_cancel; otherwise the callbackof a completed request would use invalid data....

Fix build
Actually some systems don't define PAGE_SIZE. Fixes build breakageby f7736b91c40a617e93505e32dcbd2cb56aad8a23.
Compile ide/core only once
Make win2k install hack unconditional as it is still restricted tox86 only in vl.c.
Replace TARGET_PAGE_SIZE and 4096 with PAGE_SIZE.
block: Emit BLOCK_IO_ERROR before vm_stop() call
The next commit will move the STOP event into do_vm_stop(), tohave the expected event sequence we need to emit the I/O errorevent before calling vm_stop().

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:
