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"]}}

To allow testing of the cpu updater function, this function needs to be
available separately. Export it from qemu_agent.c where it should
belong.

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.

Add a function qemuAgentArbitraryCommand() for general qemu agent command.

Except a bunch of files for security driver, all others are changed

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.

monitor command is available.

These functions simply issue command to guest agent which
should freeze or unfreeze all file systems within guest.

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
