Get mounted filesystems list, which contains hardware info of disks and its
controllers, from QEMU guest agent 2.2+. Then, convert the hardware info
to corresponding device aliases for the disks.

One caveat though, qemu-ga is expecting time and returning time
in nanoseconds. With all the buffering and propagation delay, the
time is already wrong once it gets to the qemu-ga, but there's
nothing we can do about it.

With this patch, virDomainFSFreeze will pass the mountpoints argument
to qemu guest agent. For example,
virDomainFSFreeze(dom, {"/mnt/vol1", "/mnt/vol2"}, 2, 0)
will issue qemu guest agent command:
{"execute":"guest-fsfreeze-freeze",
"arguments":{"mountpoints":["/mnt/vol1","/mnt/vol2"]}}

The qemu guest agent allows to online and offline CPUs from the
perspective of the guest. This patch adds helpers that call
'guest-get-vcpus' and 'guest-set-vcpus' guest agent functions and
convert the data for internal libvirt usage.
The virDomainObj, qemuAgent, qemuMonitor, lxcMonitor classes
all require a mutex, so can be switched to use virObjectLockable

using qemu guest agent. As said in previous patch,
@mountPoint must be NULL and @flags zero because
qemu guest agent doesn't support these arguments
yet. If qemu learns them, we can start supporting
them as well.

When reboot using qemu guest agent was requested, qemu driver kept
waiting for SHUTDOWN event from qemu. However, such event is never
emitted during guest reboot and qemu driver would keep waiting forever.

This patch removes the explicit FSF address, and uses above instead

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:

With latest changes to qemu-ga success on some commands is not reported
anymore, e.g. guest-shutdown or guest-suspend-*. However, errors are
still being reported. Therefore, we need to find different source of
indication if operation was successful. Events.
There is now a standard QEMU guest agent that can be installed
and given a virtio serial channel
<channel type='unix'>
<source mode='bind' path='/var/lib/libvirt/qemu/f16x86_64.agent'/>
<target type='virtio' name='org.qemu.guest_agent.0'/>
</channel>
The protocol that runs over the guest agent is JSON based and
very similar to the JSON monitor. We can't use exactly the same
code because there are some odd differences in the way messages
and errors are structured. The qemu_agent.c file is based on
a combination and simplification of qemu_monitor.c and
qemu_monitor_json.c
* src/qemu/qemu_agent.c, src/qemu/qemu_agent.h: Support for
talking to the agent for shutdown
* src/qemu/qemu_domain.c, src/qemu/qemu_domain.h: Add thread
helpers for talking to the agent
* src/qemu/qemu_process.c: Connect to agent whenever starting

* src/qemu/qemu_monitor_json.c: Make variable static
