This patch adds a few stub implementations for MMC commands to
scsi-disk, to be filled in later in the series. It also adds to
scsi-defs.h constants for commands implemented by ide/atapi.c,
when missing.

Building on the previous patch, this one adds a media change callback

Reporting media change events via unit attention sense codes requires
a small state machine: first report "NO MEDIUM", then report "MEDIUM MAY
HAVE CHANGED". Unfortunately there is no good hooking point for the
device to notice that its pending unit attention condition has been
reported. This patch reworks the generic machinery to add one.

The first two bytes (after the 8-byte ATAPI header) are the mode page
number and the number of bytes after the length field itself. Make
this clear in the code.
The AUDIO_CTL page was filled with wrong values. It is not anymore in
MMC, but at least keep the values sane.

As a complement to the previous patch, move definitions for GET EVENT
STATUS NOTIFICATION from the two functions to scsi-defs.h.
The NCR_* constants are just bit values corresponding to the ENC_*
values, with no offsets even, so keep just one copy.

The definitions in ide/internal.h are duplicates, since ATAPI commands
actually come from SCSI. Use the ones in scsi-defs.h and move the
missing ones there. Two exceptions:
- MODE_PAGE_WRITE_PARMS conflicts with the "flexible disk geometry"
page in scsi-disk.c. It is unused, so pick the latter.
- GPCMD_* is left in ide/internal.h, at least for now.

This also fixes a bug with the old version: QMP would invert device id
and vendor id. This would look ok on HMP because it was printing
"device:vendor" instead of "vendor:device".

Please, note that some of the code supporting memory statistics is
still around (eg. virtio_balloon_receive_stats() and reset_stats()).
Also, the qmp_query_balloon() function is synchronous and thus doesn't
make any use of the (not fully working) monitor's asynchronous command
support (the old non-qapi implementation did).

Windows 7 may use the same stream number for input and output.
Current code will confuse streams.
Changes since v1:
- keep running_compat[] for migration version 1
- add running_real[] for migration version 2

Windows 7 may use the same stream number for input and output.
That will result in lot of garbage on playback.
The hardcoded value of 4 needs to be in sync with GCAP streams
description and IN/OUT registers.

update init_qxl_ram to reset update_surface to 0. This fixes one case
of breakage when installing an old driver in a vm that had a new driver
installed. The newer driver would know about surface creation and would
change update_surface to !=0, then a reset would happen, all surfaces
are destroyed, then the old driver is initialized and issues an
UPDATE_AREA, and spice server aborts on invalid surface.

(1) If the guest cursor command is empty, don't reload it after migration.
(2) Cleaning the guest cursor when it is released by
the spice server. In addition, explicitly reset the
cursor in spice upon destroying the primary surface
(was done by spice-server implicitly). This will prevent
access to pci memory that was released.

This was only a best-effort attempt, by far not guaranteed to have an

Use QEMU thread API instead of pthread directly. We still need to get

Fix incorrect order of arguments, letting writes to NVRAM succeed.
It looks like guests never write to the device, only read from it, since the bug

Commit 63ffb564 broke floppy devices specified on the command line like
-drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it
relies on drive_get() which works only with -fda/-drive if=floppy.
This patch resembles what we're already doing for IDE, i.e. remember the floppy
device that was created and use that to extract the BlockDriverStates where
needed.

The floppy device was broken by commit 212ec7ba (fdc: Convert to
isa_register_portio_list). While the old interface provided the port number
relative to the floppy drive's io_base, the new one provides the real port
number, so we need to apply a bitmask now to get the register number.

The synchronous .bdrv_flush callback doesn't exist any more and a device really
shouldn't poke into the block layer internals anyway. All drivers are supposed
to have a correctly working bdrv_flush, so let's just hard-code this.
