All vbox objects are child objects from the nsISupports in vbox's
C++ API version. Since the CAPI is generated from the C++ API, I
kept their relationship here, by the definitations below:

typedef struct nsISupports nsISupports;
typedef nsISupports IVirtualBox;
typedef nsISupports ISession;
and so on...

So, when calling the API from nsISupports, we don't need to do
typecasting, and things work still work well.

Introduce vbox_uniformed_api to deal with version conflicts. Use
vbox_install_api to register the currect vboxUniformedAPI with
vbox version.

vboxConnectOpen has been rewritten.

Martin Kletzander pointed out in email that my commit 2a193f64
introduced a crash in networkCreateInterfacePool() during startup of
any network that doesn't have a <pf> subelement of its <forward>
element. He also supplied a patch.

 http://www.redhat.com/archives/libvir-list/2014-August/msg00655.html

I expanded on that patch by cleaning up now-extraneous checks in the
callers of networkCreateInterfacePool().

Fortunately the offending patch hasn't been in any release, and hasn't
been (to my knowledge) backported to any other branch.

The gid value passed to devpts has to be translated by hand as
virLXCControllerSetupDevPTS() is called before setting up the user
and group mappings.
Otherwise devpts will use an unmapped gid and openpty()
will fail within containers.

During a QEMU live migration several warning messages about job
handling could be written to syslog on the destination host:

"entering monitor without asking for a nested job is dangerous"

The messages are written because the job handling during migration
uses hard coded asyncJob values in several places that are incorrect.

This patch passes the required asyncJob value around and prevents
the warnings as well as any issues that the warnings may be referring
to.

commit d9504941 introduces two new attributes "cmd_per_lun" and
"max_sectors" same with the names QEMU uses for virtio-scsi.
But the case of parsing them is not exact. Change to parse
them if controller has "driver" element.

This patch changes the setmaxmem function to support the '--live',
'--config', and '--current' flags by revectoring the code through
the setmem function using the VIR_DOMAIN_MEM_MAXIMUM flag. The
setmem code is refactored to handle both cases depending on the flag.

The changed maxmem code for the MEM_MAXIMUM path will not allow
modification to the memory values of an active guest unless the --config
switch is used.

If we failed to create BHYVE_STATE_DIR, we should show this
path, not BHYVE_LOG_DIR.

At the beginning of the qemu config file parsing function there
are 3 helper macros defined: GET_VALUE_BOOL, GET_VALUE_LONG and
GET_VALUE_STR. Later, when they are no longer needed they are
undefined in order to keep the namespace clean. However, the
GET_VALUE_STRING is undefined instead of GET_VALUE_STR.

Implement ZFS storage backend driver. Currently supported
only on FreeBSD because of ZFS limitations on Linux.

Features supported:

 - pool-start, pool-stop
 - pool-info
 - vol-list
 - vol-create / vol-delete

Pool definition looks like that:

 <pool type='zfs'>
  <name>myzfspool</name>
  <source>
    <name>actualpoolname</name>
  </source>
 </pool>

The 'actualpoolname' value is a name of the pool on the system,
such as shown by 'zpool list' command. Target makes no sense
here because volumes path is always /dev/zvol/$poolname/$volname.

User has to create a pool on his own, this driver doesn't
support pool creation currently.

A volume could be used with Qemu by adding an entry like this:

    <disk type='volume' device='disk'>
      <driver name='qemu' type='raw'/>
      <source pool='myzfspool' volume='vol5'/>
      <target dev='hdc' bus='ide'/>
    </disk>

In qemuMigrationToFile we enter the monitor multiple times and don't
check if the VM is still alive after returning form the monitor. Add the
checks to skip pieces of code in case the VM crashes while saving it's
state.

Saving a shutoff VM doesn't make sense and libvirtd crashes while
attempting to do that. Check that the domain is alive after entering
the save async job.
