block: Introduce bdrv_pwritev() for qcow2_save_vmstate

Directly pass the QEMUIOVector on instead of linearising it.

aes: move aes.h from include/block to include/qemu

Move aes.h from include/block to include/qemu to show it can be reused
by other subsystems.

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

qcow2: Return real error in qcow2_update_snapshot_refcount

This fixes the error message triggered by the following script:

cat > /tmp/blkdebug.cfg <&lt;EOF
    [inject-error]
    event = "cluster_free" 
    errno = "28" 
    immediately = "off" 
    EOF

qcow2: Fix L1 write error handling in qcow2_update_snapshot_refcount

It ignored the error code, and at least the 'goto fail' is obvious
nonsense as it creates an endless loop (if the next attempt doesn't
magically succeed) and leaves the in-memory L1 table in big-endian...

oslib-posix: rename socket_set_nonblock() to qemu_set_nonblock()

The fcntl(fd, F_SETFL, O_NONBLOCK) flag is not specific to sockets.
Rename to qemu_set_nonblock() just like qemu_set_cloexec().

qcow2: Allow requests with multiple l2metas

Instead of expecting a single l2meta, have a list of them. This allows
to still have a single I/O request for the guest data, even though
multiple l2meta may be needed in order to describe both a COW overwrite
and a new cluster allocation (typical sequential write case)....

qcow2: Move cluster gathering to a non-looping loop

This patch is mainly to separate the indentation change from the
semantic changes. All that really changes here is that everything moves
into a while loop, all 'goto done' become 'break' and at the end of the...

qcow2: Gather clusters in a looping loop

Instead of just checking once in exactly this order if there are
dependendies, non-COW clusters and new allocation, this starts looping
around these. This way we can, for example, gather non-COW clusters after
new allocations as long as the host cluster offsets stay contiguous....
