qcow2: Correct bitmap size in zero expansion
Since the expanded_clusters bitmap is addressed using host offsets in
the underlying image file, the correct size to use for allocating the
bitmap is not determined by the guest disk image but by the underlying
host image file.
Furthermore, this size may change during the expansion due to cluster
allocations on growable image files. In this case, the bitmap needs to
be resized as well to reflect the growth.

qemu-iotests: Add basic ability to use binary sample images
For image formats that are not "QEMU native", but supported for
compatibility, it is useful to verify that an image created with
the 'gold standard' native tool can be read / written to successfully
by QEMU.
In addition to testing non-native images, this could also be useful to
test against image files created by older versions of QEMU.
This provides a directory to store small sample images, for use by
scripts in tests/qemu-iotests.
Image files should be compressed with bzip2.
To use a sample image from a bash script, the _use_sample_img function
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
be the decompressed sample image copy. To cleanup, call
_cleanup_test_img as normal.

virtio-blk: do not relay a previous driver's WCE configuration to the current
The following sequence happens:
- the SeaBIOS virtio-blk driver does not support the WCE feature, which
causes QEMU to disable writeback caching
- the Linux virtio-blk driver resets the device, finds WCE is available
but writeback caching is disabled; tells block layer to not send cache
flush commands
- the Linux virtio-blk driver sets the DRIVER_OK bit, which causes
writeback caching to be re-enabled, but the Linux virtio-blk driver does
not know of this side effect and cache flushes remain disabled
The bug is at the third step. If the guest does know about CONFIG_WCE,
QEMU should ignore the WCE feature's state. The guest will control the
cache mode solely using configuration space. This change makes Linux
do flushes correctly, but Linux will keep SeaBIOS's writethrough mode.
Hence, whenever the guest is reset, the cache mode of the disk should
be reset to whatever was specified in the "-drive" option. With this
change, the Linux virtio-blk driver finds that writeback caching is
enabled, and tells the block layer to send cache flush commands
appropriately.

target-i386: Fix segment cache dump
When in Long Mode, cpu_x86_seg_cache() logs "DS16" because the Default
operation size bit (D/B bit) is not set for Long Mode Data Segments since
there are only Data Segments in Long Mode and no explicit 16/32/64-bit
Descriptors.
This patch fixes this by checking the Long Mode Active bit of the hidden
flags variable and logging "DS" if it is set. (I.e. in Long Mode all Data
Segments are logged as "DS")

Debian busybox-static for alpha has a load address of 0x0000000120000000

Secondly it's always more efficient to avoid copying the guest

qxl: simplify page dirtying
No need to do target page size calculations here,
memory_region_set_dirty will care for us.

qxl: simplify qxl_rom_size
Nowdays rom size is fixed at 8192 for live migration compat reasons.
So we can ditch the pointless math trying to calculate the size needed.
Also make the size sanity check fail at compile time not runtime.

block/iscsi: Drop iscsi_co_get_block_status for older versions of libiscsi
Debian wheezy includes libiscsi-dev 1.4.0 which does not provide
SCSI_PROVISIONING_TYPE_DEALLOCATED. Drop iscsi_co_get_block_status
in this case to allow compilation without errors.
