0eb28a4228 BlockConf: Call backend functions to detect geometry and blocksizes
geometry: hd_geometry_guess function autodetects the drive geometry.
This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.

blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise
it will set default 512 value.

The blkconf_blocksizes call was added to all users of BlkConf.

9b3d111ad9 hw: Propagate errors through qdev_prop_set_drive()
Three kinds of callers:

1. On failure, report the error and abort

   Passing &error_abort does the job.  No functional change.

2. On failure, report the error and exit()

   This is qdev_prop_set_drive_nofail().  Error reporting moves from
   qdev_prop_set_drive() to its caller.  Because hiding away the error
   in the monitor right before exit() isn't helpful, replace
   qerror_report_err() by error_report_err().  Shouldn't make a
   difference, because qdev_prop_set_drive_nofail() should never be
   used in QMP context.

3. On failure, report the error and recover

   This is usb_msd_init() and scsi_bus_legacy_add_drive().  Error
   reporting and freeing the error object moves from
   qdev_prop_set_drive() to its callers.

   Because usb_msd_init() can't run in QMP context, replace
   qerror_report_err() by error_report_err() there.

   No functional change.

   scsi_bus_legacy_add_drive() calling qerror_report_err() is of
   course inappropriate, but this commit merely makes it more obvious.
   The next one will clean it up.

25f8dd9659 qdev: Don't exit when running into bad -global
-global lets you set a nice booby-trap for yourself:

    $ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
    QEMU 2.1.94 monitor - type 'help' for more information
    (qemu) device_add usb-mouse
    Parameter 'usb_version' expects an int64 value or range
    $ echo $?
    1

Not nice.  Until commit 3196270 we even abort()ed.

The same error triggers if you manage to screw up a machine type's
compat_props.  To demonstrate, change HW_COMPAT_2_1's entry to

            .driver   = "usb-mouse",\
            .property = "usb_version",\
            .value    = "1", \

Then run

    $ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
    upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
    $ echo $?
    1

One of our creatively cruel error messages.

Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.

But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user.  Looks like this:

    $ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
    QEMU 2.1.94 monitor - type 'help' for more information
    (qemu) device_add usb-mouse
    Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
    (qemu)

This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().

You could argue that the error should make device_add fail.  Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.

4be746345f hw: Convert from BlockDriverState to BlockBackend, mostly
Device models should access their block backends only through the
block-backend.h API.  Convert them, and drop direct includes of
inappropriate headers.

Just four uses of BlockDriverState are left:

* The Xen paravirtual block device backend (xen_disk.c) opens images
  itself when set up via xenbus, bypassing blockdev.c.  I figure it
  should go through qmp_blockdev_add() instead.

* Device model "usb-storage" prompts for keys.  No other device model
  does, and this one probably shouldn't do it, either.

* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
  blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
  which has only the BlockDriverState.

* PC87312State has an unused BlockDriverState[] member.

The next two commits take care of the latter two.

9f9260a3be qdev: Display warning about unused -global
This can help a user understand why -global was ignored.

For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.

This is currently clear when the wrong property is provided:

out/x86_64-softmmu/qemu-system-x86_64 -global cirrus-vga.vram_size_mb=16 -monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)

39f72ef94b qom: Add check() argument to object_property_add_link()
There are currently three types of object_property_add_link() callers:

1. The link property may be set at any time.
2. The link property of a DeviceState instance may only be set before
   realize.
3. The link property may never be set, it is read-only.

Something similar can already be achieved with
object_property_add_str()'s set() argument.  Follow its example and add
a check() argument to object_property_add_link().

Also provide default check() functions for case #1 and #2.  Case #3 is
covered by passing a NULL function pointer.

6e4a876b43 iothread: add "iothread" qdev property type
Add a "iothread" qdev property type so devices can be hooked up to an
IOThread from the comand-line:

  qemu -object iothread,id=iothread0 \
       -device some-device,x-iothread=iothread0

Note that Paolo Bonzini <pbonzini@redhat.com> has suggested using QOM
links instead.  This way the relationship between the objects is
reflected in QOM.  There are currently shortcomings of
object_property_add_link() which prevent this use case.  I will attempt
to fix them and move to QOM links in a separate series.
