Currently, for the pseries machine the device tree supplied by qemu to SLOF
and from there to the guest does not include a 'compatible property' at the
root level. Usually that works fine, since in this case the compatible
property doesn't really give any information not already found in the
'device_type' or 'model' properties.
However, the lack of 'compatible' confuses the bootloader install in the
SLES11 SP2 and SLES11 SP3 installers. This patch therefore adds a token
'compatible' property to work around that.

The current elf loader uses too much memory. For example, I have a
executable with a bss section of 400 MB and I set the ram size to 512
MB. Qemu uses about 780MB of RAM (which is fine), but there's a peak at
1.6 GB during initialization (this is not fine).
This patch fixes two things:
1) do not allocate each elf program twice.
2) do not allocate memory for areas that are only zeros.
For this we need a new field in Rom: "datasize" which is the size of the
allocated data. If datasize is less than romsize, it means that the area
from datasize to romsize is filled with zeros.

The BIT6 of Status Register(SR):
SR[6] behaves the same as R/B# pin
SR[6] = 0 indicates the device is busy;
SR[6] = 1 means the device is ready
Some NAND flash controller (i.e. ftnandc021) relies on the SR[6]
to determine if the NAND flash erase/program is success or error timeout.

Always check it immediately after calling bdrv_acct_done, and
always do a "goto done" in case the "done" label has to free
some memory---as is the case for scsi_unmap_complete in the
previous patch.
This patch could fix problems that happen when a request is
split into multiple parts, and one of them is canceled. Then
the next part is fired, but the HBA's cancellation callbacks have
fired already. Whether this happens or not, depends on how the
block/ driver implements AIO cancellation. It it does a simple
bdrv_drain_all() or similar, then it will not have a problem.
If it only cancels the given AIOCB, this scenario could happen.

During the review of the dataplane code, the EventPoll API morphed itself
(not concidentially) into something very very similar to an AioContext.
Thus, it is trivial to convert virtio-blk-dataplane to use AioContext,
and a first baby step towards letting dataplane talk directly to the
QEMU block layer.
The only interesting note is the value-copy of EventNotifiers. At least
in my opinion this is part of the EventNotifier API and is even portable
to Windows. Of course, in this case you should not close the notifier's
underlying file descriptors or handle with event_notifier_cleanup.
