Reorganize struct Qcow2Cache for better struct packing

Move size after the two pointers in struct Qcow2Cache to get better
packing of struct elements on 64 bit architectures.

sheepdog: support creating images on remote hosts

This patch parses the input filename in sd_create(), and enables us
specifying a target server to create sheepdog images.

qcow2: Add bdrv_discard support

This adds a bdrv_discard function to qcow2 that frees the discarded clusters.
It does not yet pass the discard on to the underlying file system driver, but
the space can be reused by future writes to the image.

qed: Images with backing file do not require QED_F_NEED_CHECK

The consistency check on open is necessary in order to fix inconsistent
table offsets left as a result of a crash mid-operation. Images with a
backing file actually flush before updating table offsets and are...

qed: Refuse to create images on block devices

QED relies on the underlying filesystem to extend the file and maintain
its size. Check that images are not created on a block device.

qcow2: Use QcowCache

Use the new functions of qcow2-cache.c for everything that works on refcount
block and L2 tables.

qcow2: Batch flushes for COW

qcow2 calls bdrv_flush() after performing COW in order to ensure that the
L2 table change is never written before the copy is safe on disk. Now that the
L2 table is cached, we can wait with flushing until we write out the next L2...

qcow2: Add QcowCache

This adds some new cache functions to qcow2 which can be used for caching
refcount blocks and L2 tables. When used with cache=writethrough they work
like the old caching code which is spread all over qcow2, so for this case we
have merely a cleanup....

qcow2: fix unaligned access

cpu_to_be64w() is called with an obviously non-aligned pointer. Use
cpu_to_be64wu() instead. It fixes unaligned accesses errors on IA64
hosts.
