[libvirt] [PATCH 4/4] vbox: add support for 4.3 APIs

Makefile.am, vbox_V4_3.c and vbox_driver.c do regular
modifitions to support a new version of APIs.
vbox_tmpl.c basically fixes incompatibilities since 4.2.
The affected incompatibilities of 4.3 are:
* IMachine::Delete() has been renamed to IMachine::deleteConfig()
* IMedium::CreateBaseStorage() now accepts multiple variant values
* IDisplay::GetScreenResolution() now returns the display position
in the guest
* IMachine now has multiple IUSBControllers and IUSBDeviceFilters
handles USB device filters instead of (obsolete) IUSBController
This patch is tested on Mac OS X 10.8.5 and Fedora 19.
