blockdev: Store -drive option media in DriveInfo

DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device. Unlike
DriveInfo, BlockDriverState should be about the host part only.

One of the remaining guest bits there is the "type hint". -drive...

block QMP: Deprecate query-block's "type", drop info block's "type="

query-block's specification documents response member "type" with
values "hd", "cdrom", "floppy", "unknown".

Its value is unreliable: a block device used as floppy has type
"floppy" if created with if=floppy, but type "hd" if created with...

defaults: ide-cd, ide-hd and scsi-cd devices suppress default CD-ROM

ide-hd has to suppress the default CD-ROM, or else you can't put one
on secondary master without -nodefaults.

Unlike legacy scsi-disk, scsi-cd suppresses default CD-ROM.

scsi: Split qdev "scsi-disk" into "scsi-hd" and "scsi-cd"

A "scsi-disk" is either a hard disk or a CD-ROM, depending on the
associated BlockDriverState's type hint. Unclean; disk vs. CD belongs
to the guest part, not the host part.

Have separate qdevs "scsi-hd" and "scsi-cd" to model disk vs. CD in...

qemu_img: is_not_zero() optimization

I run qemu-img under profiler and realized, that most of CPU time is
consumed by is_not_zero() function. I had made a couple of optimizations
on it and got the following output for `time qemu-img convert -O qcow2
volume.qcow2 snapshot.qcow2`:...

qed: support for growing images

The .bdrv_truncate() operation resizes images and growing is easy to
implement in QED. Simply check that the new size is valid and then
update the image_size header field to reflect the new size.

ahci: Fix crashes on duplicate BH registration

If ahci_dma_set_inactive is called a while there is still a pending BH
from a previous run, we will crash on the second run of
ahci_check_cmd_bh as it overwrites AHCIDevice::check_bh. Avoid this
broken and redundant duplicate registration....

qemu-tool: Stub out qemu-timer functions

Block drivers may use timers for flushing metadata to disk or
reconnecting to a network drive. Stub out the following functions in
qemu-tool.c:

QEMUTimer *qemu_new_timer_ns(QEMUClock *clock, int scale,
QEMUTimerCB *cb, void *opaque)...

qed: Periodically flush and clear need check bit

One strategy to limit the startup delay of consistency check when
opening image files is to ensure that the file is marked dirty for as
little time as possible.

QED currently marks the image dirty when the first allocating write...
