Using the new host_net_redir command you can easily create redirections
on the fly while your VM is running.

While that's great, it's missing the removal of redirections, in case you
want to have a port closed again at a later point in time.

This patch adds support for removal of redirections.

All,
     I've recently been playing around with migration via exec.  Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened.  This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time.  This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.

(note: developed/tested with qemu-kvm, but applies perfectly fine to qemu)

Now that we have a separate aio pool structure we can remove those
aio pool details from BlockDriver.

Every driver supporting AIO now needs to declare a static AIOPool
with the aiocb size and the cancellation method.  This cleans up the
current code considerably and will make it cleaner and more obvious
to support two different aio implementations behind a single
BlockDriver.

We do need hdev_create unconditionally on all platforms so that qemu-img
create support for host device works on all platforms.

Also relax the check to allow character devices in addition to block
devices.  On many Unix platforms block devices have buffered block
nodes and unbuffered character device nodes, and on FreeBSD the block
nodes don't even exist anymore.  Also on Linux we do support the
/dev/sgN scsi passthrough devices through the host device driver,
and probably the old-style /dev/raw/rawN raw devices although I haven't
tested that.

raw_pread_aligned currently returns the raw return value from
lseek/read, which is always -1 in case of an error.  But the
callers higher up the stack expect it to return the negated
errno just like raw_pwrite_aligned.

Pointer vs addresses a VncDisplay structure,
so it is sufficient to allocate sizeof(VncDisplay)
or sizeof(*vs) bytes instead of the much larger
sizeof(VncState).

Maybe the misleading name should be fixed, too:
the code contains many places where vs is used,
sometimes it is a VncState *, sometimes it is a
VncDisplay *. vd would be a better name.

Commit ffad4116 removed the "scratch buffer"
from check_params, but didn't care for the error messages which actually
included this string to tell the user which option was wrong. Now this string
is uninitialized, so this patch removes it from the message.

This means that the user is only told the whole parameter string and has to
pick the wrong option by himself as the callers of check_params can't know this
value any more. An alternative approach would be to revert that commit and do
whatever is needed to fix the original problem without changing check_params.

Implement and use a common device bus state.  The main side-effect is
that creating a bus and attaching it to a parent device are no longer

should go away eventually.
