[pve-devel] applied: live storage migration v9

[Wolfgang Bumiller]

Applied the series with some followup patches:
* Added patches for the timeout and POSIX::_exit() changes I mentioned.
* Also added some whitespace & style cleanup patches.

Now we need to figure out whether to first add the ssh-tunnel based
ecnryption or go with qemu's tls. Saw the thread on qemu-devel about
nbd&tls and blockdev-add - sounds inconvenient until we're >= 2.8.
(There's also one about the nbd handshake being able to block qemu's
main thread... should be hard to trigger, plus the socat timeout should
catch this as well AFAIK.)

Sending the followup patches to the list now.
