The check on the max_table_size field not being larger than required is
valid, and in accordance with the VHD spec. However, there have been
VHD images encountered in the wild that have an out-of-spec max table
size that is technically too large.
There is no issue in allowing this larger table size, as we also
later verify that the computed size (used for the pagetable) is
large enough to fit all sectors. In addition, max_table_entries
is bounds checked against SIZE_MAX and INT_MAX.
Remove the strict check, so that we can accomodate these sorts of
images that are benignly out of spec.

The old VHD_MAX_SECTORS value is incorrect, and is a throwback
to the CHS calculations. The VHD specification allows images up to 2040
GiB, which (using 512 byte sectors) corresponds to a maximum number of
sectors of 0xff000000, rather than the old value of 0xfe0001ff.
Update VHD_MAX_SECTORS to reflect the correct value.
Also, update comment references to the actual size limit, and correct
one compare so that we can have sizes up to the limit.

Commit 57d6a428 broke blk_aio_write_zeroes() because in some write
functions in the call path don't have an explicit length argument but
reuse qiov->size instead. Which is great, except that write_zeroes
doesn't have a qiov, which this commit interprets as 0 bytes.
Consequently, blk_aio_write_zeroes() didn't effectively do anything.
This patch introduces an explicit acb->bytes in BlkAioEmAIOCB and uses
that instead of acb->rwco.size.
The synchronous version of the function is okay because it does pass a
qiov (with the right size and a NULL pointer as its base).

The balloon code currently calls madvise() with TARGET_PAGE_SIZE as
length parameter. Since the virtio-balloon protocol is always based
on 4k pages, no matter what the host and guest are using as page size,
this could cause problems: If TARGET_PAGE_SIZE is bigger than 4k, the
madvise call also destroys the 4k areas after the current one - which
might be wrong since the guest did not want free that area yet (in
case the guest used as smaller MMU page size than the hard-coded
TARGET_PAGE_SIZE). So to fix this issue, introduce a proper define
called BALLOON_PAGE_SIZE (which is 4096) to use this as the size
parameter for the madvise() call instead.

IRQ 5 used by TPM conflicts with PNP0C0F IRQs,
as result Windows fails driver initialization with reason
'device cannot find enough free resources'
But if TPM._CRS.IRQ entry is commented out, Windows
seems to initialize driver without errors as it doesn't
notice possible conflict and it seems to work
probably due to a link with IRQ 5 being unused/disabled.
So temporary comment out TPM._CRS.IRQ to 'fix'
regression in TPM, with intent to fix it correctly
later i.e.:
1. pick unused IRQ as default one for TPM
2. fetch IRQ value from device model so that user
could override default one if it conflicts with
some other device.

Restart of ATAPI DMA used to be unreachable, because the request to do
so wasn't indicated in bus->error_status due to the lack of spare bits, and
ide_restart_bh() would return early doing nothing.
This patch makes use of the observation that not all bit combinations were
possible in ->error_status. In particular, IDE_RETRY_READ only made sense
together with IDE_RETRY_DMA or IDE_RETRY_PIO. This allows to re-use
IDE_RETRY_READ alone as an indicator of ATAPI DMA restart request.
To makes things more uniform, ATAPI DMA gets its own value for ->dma_cmd.
As a means against confusion, macros are added to test the state of
->error_status.
The patch fixes the restart of both in-flight and pending ATAPI DMA,
following the scheme similar to that of IDE DMA.

If the migration occurs after the IDE DMA has been set up but before it
has been initiated, the state gets lost upon save/restore. Specifically,
->dma_cb callback gets cleared, so, when the guest eventually starts bus
mastering, the DMA never completes, causing the guest to time out the
operation.
OTOH all the infrastructure is already in place to restart the DMA if
the migration happens while the DMA is in progress.
So reuse that infrastructure, by setting bus->error_status based on
->dma_cmd in pre_save if ->dma_cb callback is already set but DMAING is
clear. This will indicate the need for restart and make sure ->dma_cb
is restored in ide_restart_bh(); howeover since DMAING is clear the state
upon restore will be exactly "ready for DMA" as before the save.

The __all__ list contained a typo for as long as the iotests module

The names used by iotests are highly prone to name collisions, so
importing them all unconditionally is a bad idea anyway. Since __all__
is not adding any value, let's just get rid of it.

qemu-iotests test case 148 already had some code for skipping the test
if quorum support is missing, but it didn't work in all
cases. TestQuorumEvents.setUp() gets run before the actual test class
(which contains the skipping code) and tries to start qemu with a drive
using the quorum driver. For some reason this works fine when using
qcow2, but fails for raw.
As the entire test case requires quorum, just check for availability
before even starting the test suite. Introduce a verify_quorum()
function in iotests.py for this purpose so future test cases can make
use of it.

Placing files with predictable or even hard-coded names in /tmp is a
security risk and can prevent or disturb operation on a multi-user
machine. Place them inside the "scratch" directory instead, as we
already do for most other test-related files.

As agreed with Kevin and already practiced for a while, I am adding
myself as co-maintainer of the block layer core, qcow2 and blkdebug.

We reject backing file names with a length of more than 1023 characters
when opening a qcow2 file, so we should not produce such files
ourselves.

bdrv_pwrite_sync used to return zero or negative error, while blk_pwrite returns
the number of written bytes when successful. This caused VPC image creation
to fail spectacularly: it wrote the first 512 bytes, and then exited immediately
because of the non-zero answer from blk_pwrite. But the truly spectacular part
is that it returns a positive value (the 512 that blk_pwrite returned) causing
everyone to believe that it succeeded.
This fixes qemu-iotests with vpc format.

The actual on-disk size of a file does not only depend on factors qemu
can control. Thus, we should not depend on this to determine whether a
file has indeed been fully allocated. Instead, use qemu-img map and hope
that if an area is referenced, it is indeed allocated, too.
Also, limit the supported image formats to raw and qcow2 because the
actual qemu-img map output may depend on the image format.
