Add a test for qemu-img commit on backing chains with more than two
images. This test also checks whether the top image is emptied (unless
this is prevented by specifying either -d or -b) and does therefore not
work for qed and vmdk which requires it to be separate from 020.

As of a follow-up patch to this one, the length of a mirror block job
will no longer directly depend on the size of the block device;
therefore, drop these checks from this test. Instead, just check whether
the final offset equals the block job length.

As 041 uses the wait_until_completed function from iotests.py, the same
applies there as well which in turn affects tests 030, 055 and 056. On
the other hand, a block job's length does not have to be related to the
length of the image file in the first place, so that check was
questionable anyway.

bdrv_make_empty() is currently only called if the current image
represents an external snapshot that has been committed to its base
image; it is therefore unlikely to have internal snapshots. In this
case, bdrv_make_empty() can be greatly sped up by emptying the L1 and
refcount table (while having the dirty flag set, which only works for
compat=1.1) and creating a trivial refcount structure.

If there are snapshots or for compat=0.10, fall back to the simple
implementation (discard all clusters).

As its comment states, raw_co_get_block_status() should unconditionally
return 0 and set *pnum to 0 for after EOF.

An assertion after lseek(..., SEEK_HOLE) tried to catch this case by
asserting that errno != -ENXIO (which would indicate a position after
the EOF); but it should be errno != ENXIO instead. Regardless of that,
there should be no such assertion at all. If bdrv_getlength() returned
an outdated value and the image has been resized outside of qemu,
lseek() will return with errno == ENXIO. Just return that value as an
error then.

Setting *pnum to 0 and returning 0 should not be done here, as in that
case we should update the device length as well. So, from qemu's
perspective, the file has not been resized; it's just that there was an
error querying sectors beyond a certain point (the actual file size).

Additionally, nb_sectors should be clamped against the image end. This
was probably not an issue if FIEMAP or SEEK_HOLE/SEEK_DATA worked, but
the fallback did not take this case into account.

qemu_opt_get_number returns a uint64_t, and curl_easy_setopt expects a
long (not an int).  There is no warning about the latter type error
because curl_easy_setopt uses a varargs argument.

Store the timeout (which is a positive number of seconds) as a
uint64_t.  Check that the number given by the user is reasonable.
Zero is permissible (meaning no timeout is enforced by cURL).

Cast it to long before calling curl_easy_setopt to fix the type error.

Currently, DMA read/write operations neglect to update
the byte count after a successful transfer like ATAPI
DMA read or PIO read/write operations do.

We correct this oversight by adding another callback into
the IDEDMAOps structure. The commit callback is called
whenever we are cleaning up a scatter-gather list.
AHCI can register this callback in order to update post-
transfer information such as byte count updates.

We use this callback in AHCI to consolidate where we delete
the SGlist as generated from the PRDT, as well as update the
byte count after the transfer is complete.

The QEMUSGList structure has an init flag added to it in order
to make qemu_sglist_destroy a nop if it is called when
there is no sglist, which simplifies cleanup and error paths.

This patch fixes several AHCI problems, notably Non-NCQ modes

Currently, the D2H FIS packets AHCI generates simply parrot back
the LBA that the guest sent to us in the cmd_fis. However, some
commands (like READ NATIVE MAX) modify the LBA registers as a
return value, through which the AHCI D2H FIS is the only response
mechanism. Thus, the D2H response should use the current register
values, not the initial ones.

This patch adjusts the LBA and drive select register responses for
PIO Setup and D2H FIS response packets.

Additionally, the PIO and D2H FIS responses copy too many bytes
from the command FIS that it is being generated from. Specifically,
byte 11 which is the Features(15:8) field for Register Host to
Device FIS packets, is instead reserved for the PIO Setup FIS and
should always be 0.
