bde25388d1 ide: drop ide_tray_state_post_load()
This is used to sync the physical tray state after migration when
using CD-ROM passthrough. However, migrating when using passthrough
is broken anyway and shouldn't be supported...

So, drop this function as it causes a problem with the DEVICE_TRAY_MOVED
event, which is going to be introduced by the next commit.

d88b1819dd block: Don't call bdrv_eject() if the tray state didn't change
It's not needed. Besides we can then assume that bdrv_eject() is
only called when there's a tray state change, which is useful to
the DEVICE_TRAY_MOVED event (going to be added in a future
commit).

329c0a48a9 block: Rename bdrv_mon_event() & BlockMonEventAction
They are QMP events, not monitor events. Rename them accordingly.

Also, move bdrv_emit_qmp_error_event() up in the file. A new event will
be added soon and it's good to have them next each other.

c9b308d20b AHCI: Fix port reset race
bdrv_aio_cancel() can trigger bdrv_aio_flush() which makes all aio
that is currently in flight finish. So what we do is:

  port reset
  detect ncq in flight
  cancel ncq
  delete ncq sg list

at which point we have double freed the sg list. Instead, with this
patch we do:

  port reset
  detect ncq in flight
  cancel ncq
  check if we are really still in flight
  delete ncq sg list

which makes things work and gets rid of the race.

6acbe4c6f1 qdev: remove baked in notion of aliases (v2)
Limit them to the device_add functionality.  Device aliases were a hack based
on the fact that virtio was modeled the wrong way.  The mechanism for aliasing
is very limited in that only one alias can exist for any device.

We have to support it for the purposes of compatibility but we only need to
support it in device_add so restrict it to that piece of code.

39bffca203 qdev: register all types natively through QEMU Object Model
This was done in a mostly automated fashion.  I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass
registration functions.

The second step was another sed-based removal of subclass registration functions
while also adding virtual functions from the base class into a class_init
function as appropriate.

Finally, a python script was used to convert the DeviceInfo structures and
qdev_register_subclass functions to TypeInfo structures, class_init functions,
and type_register_static calls.

We are almost fully converted to QOM after this commit.

Back when I made patches introducing dma_addr_t and various PCI DMA
wrapper functions, I made a mistake.  The bmdma_addr_{read,write} functions
need to take target_phys_addr_t not dma_addr_t, since they are assigned
to MemoryRegionOps callbacks.

922453bca6 block: convert qemu_aio_flush() calls to bdrv_drain_all()
Many places in QEMU call qemu_aio_flush() to complete all pending
asynchronous I/O.  Most of these places actually want to drain all block
requests but there is no block layer API to do so.

This patch introduces the bdrv_drain_all() API to wait for requests
across all BlockDriverStates to complete.  As a bonus we perform checks
after qemu_aio_wait() to ensure that requests really have finished.

Mode page 2A of emulated ATAPI DVD-ROM should have page length 0x14
like SCSI CD-ROM, rather than 0x12.

Mode page length is off by 8, as it should contain the length of the

MODE SENSE(6) should be thrown out of ATAPI DVD-ROM emulation.  It is
not specified in the ATAPI list of MMC-2, and MMC-5 prescribes to use
MODE SENSE(10).  Anyway, its implementation is wrong.

0461d5a699 RunState: Rename enum values as generated by the QAPI
Next commit will convert the query-status command to use the
RunState type as generated by the QAPI.

In order to "transparently" replace the current enum by the QAPI
one, we have to make some changes to some enum values.

As the changes are simple renames, I'll do them in one shot. The
changes are:

 - Rename the prefix from RSTATE_ to RUN_STATE_
 - RUN_STATE_SAVEVM to RUN_STATE_SAVE_VM
 - RUN_STATE_IN_MIGRATE to RUN_STATE_INMIGRATE
 - RUN_STATE_PANICKED to RUN_STATE_INTERNAL_ERROR
 - RUN_STATE_POST_MIGRATE to RUN_STATE_POSTMIGRATE
 - RUN_STATE_PRE_LAUNCH to RUN_STATE_PRELAUNCH
