iscsi: Set bs->request_alignment

The iSCSI backend already gets the block size from the READ CAPACITY
command it sends. Save it so that the generic block layer gets it
too.

blkdebug: Make required alignment configurable

The new 'align' option of blkdebug can be used in order to emulate
backends with a required 4k alignment on hosts which only really require
512 byte alignment.

raw: Probe required direct I/O alignment

Add a bs->request_alignment field that contains the required
offset/length alignment for I/O requests and fill it in the raw block
drivers. Use ioctls if possible, else see what alignment it takes for
O_DIRECT to succeed....

block: Move initialisation of BlockLimits to bdrv_refresh_limits()

This function separates filling the BlockLimits from bdrv_open(), which
allows it to call it from other operations which may change the limits
(e.g. modifications to the backing file chain or bdrv_reopen)...

block: Update BlockLimits when they might have changed

When reopening with different flags, or when backing files disappear
from the chain, the limits may change. Make sure they get updated in
these cases.

block: resize backing image during active layer commit, if needed

If the top image to commit is the active layer, and also larger than
the base image, then an I/O error will likely be returned during
block-commit.

For instance, if we have a base image with a virtual size 10G, and a...

will sometimes rely on being called back on the timeout if there are...
