And provide domain summary stat in that case, for lxc backend.
Use case is a container inheriting all devices from the host,
e.g. when doing application containerization.

Adds lxcDomainBlockStatsFlags and lxcDomainBlockStats functions.

To reuse this from other drivers, like lxc.

This reads blkio stats from blkio.throttle.io_service_bytes and
blkio.throttle.io_serviced.

When start a guest with --pass-fd, if the argument of --pass-fd is invalid,
virsh will exit, but doesn't free the variable 'dom'.

IN6ADDR_ANY_INIT does not seem to be working as expected on MinGW:
error: missing braces around initializer [-Werror=missing-braces]
         .sin6_addr = IN6ADDR_ANY_INIT,

Use the in6addr_any variable instead.

Currently, networkRunHook() is called in networkAllocateActualDevice and
friends. These functions, however, doesn't necessarily work on networks,
For example, if domain's interface is defined in this fashion:

    <interface type='bridge'>
      <mac address='52:54:00:0b:3b:16'/>
      <source bridge='virbr1'/>
      <model type='rtl8139'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
    </interface>

The networkAllocateActualDevice jumps directly onto 'validate' label as
the interface is not type of 'network'. Hence, @network is left
initialized to NULL and networkRunHook(network, ...) is called. One of
the things that the hook function does is dereference @network. Soupir.

This function, which only has five call sites, simply calls
libxl_domain_destroy and libxlVmCleanup.  Call those functions
directly at the call sites, allowing more control over how a
domain is destroyed and cleaned up.  This patch maintains the
existing semantic, leaving changes to a subsequent patch.

This patch changes network device type used by default from rtl8139

At this point it has a limited functionality and is highly
experimental. Supported domain operations are:

  * define
  * start
  * destroy
  * dumpxml
  * dominfo

It's only possible to have only one disk device and only one
network, which should be of type bridge.

There might be some use cases, where user wants to prepare the host or
its environment prior to starting a network and do some cleanup after
the network has been shut down. Consider all the functionality that
libvirt doesn't currently have as an example what a hook script can
possibly do.
