The ARM devboard models (vexpress-a9, realview, versatilepb, etc)
were accidentally trying to set one of the arm_sysctl properties
after device init. This has now become a fatal error; set the property
before device init where it should be done instead.

In some cases, a legacy property does need a special print method
but not a special parse method. In this case, we can reuse the get/set
from the static (non-legacy) property.
If neither parse nor print is needed, though, do not register the
legacy property at all. The previous patch ensures that the right
fallback will be used.

There's no need to call into ->parse and ->print manually. The
QOM legacy properties do that for us.
Furthermore, in some cases legacy and static properties have exactly
the same behavior, and we could drop the legacy properties right away.
Add an appropriate fallback to prepare for this.

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.

v1 -> v2
- Use a table for aliases (Paolo)
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.

Bugfix after reboot when vmmouse was enabled and another OS which uses e.g. PS/2
mouse.
Details:
When a guest activated the vmmouse followed by a reboot the vmmouse was still
enabled and the PS/2 mouse was therefore unsusable. When another guest is then
booted without vmmouse support (e.g. PS/2 mouse) the mouse is not working.
Reason is that VMMouse has priority and disables all other mouse entities
and therefore must be disabled on reset.
Testscenario:
1.) Boot e.g. OS with VMMouse support (e.g. Windows with VMMouse tools)
2.) reboot
3.) Boot e.g. OS without VMMouse support (e.g. DOS) => PS/2 mouse doesn't work
any more. Fixes that issue.
Testscenario 2 by Jan Kiszka <jan.kiszka@siemens.com>:
Confirm that this patch fixes a real issue. Setup: qemu.git,
opensuse 11.4 guest, SDL graphic, system_reset while guest is using the
vmmouse. Without the patch, the vmmouse become unusable after the
reboot. Also, the mouse stays in absolute mode even before X starts again.
Fixed by:
Disabling the vmmouse in its reset handler.

Potentially tick-generating timer devices will gain a common property:
lock_tick_policy. It allows to encode 4 different ways how to deal with
tick events the guest did not process in time:
discard - ignore lost ticks (e.g. if the guest compensates for them
already)
delay - replay all lost ticks in a row once the guest accepts them
again
merge - if multiple ticks are lost, all of them are merged into one
which is replayed once the guest accepts it again
slew - lost ticks are gradually replayed at a higher frequency than
the original tick
Not all timer device will need to support all modes. However, all need
to accept the configuration via this common property.

When 2c74c2cb4b added support for
the 'readonly' flag against 9p filesystems, it also made QEMU
add the O_NOATIME flag as a side-effect.
The O_NOATIME flag, however, may only be set by the file owner,
or a user with CAP_FOWNER capability. QEMU cannot assume that
this is the case for filesytems exported to QEMU.
eg, run QEMU as non-root, and attempt to pass the host OS
filesystem through to the guest OS with readonly enable.
The result is that the guest OS cannot open any files at
all.
If O_NOATIME is really required, it should be optionally
enabled via a separate QEMU command line flag.
