block/raw: Add create_options for host_device

Today host_devices have a create function, so they also need a create_options
field to prevent qemu-img from complaining.

qcow2: Increase maximum cluster size to 2 MB

This patch increases the maximum qcow2 cluster size to 2 MB. Starting with 128k
clusters, L2 tables span 2 GB or more of virtual disk space, causing 32 bit
truncation and wraparound of signed integers. Therefore some variables need to...

Check availability of uuid header / library

If available, the Universally Unique Identifier library
is used by the vdi block driver.

Other parts of QEMU (vl.c) could also use it.

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

Some not so obvious bits, slirp and Xen were left alone for the time
being.

Fix sys-queue.h conflict for good

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,...

block: use fdatasync instead of fsync if possible

If we are flushing the caches for our image files we only care about the
data (including the metadata required for accessing it) but not things
like timestamp updates. So try to use fdatasync instead of fsync to...

block: add aio_flush operation

Instead stalling the VCPU while serving a cache flush try to do it
asynchronously. Use our good old helper thread pool to issue an
asynchronous fdatasync for raw-posix. Note that while Linux AIO
implements a fdatasync operation it is not useful for us because...
