[libvirt] [PATCH] 1/3 add support for netcf XML import and export

Basically this implement the routines to read an netcf XML definition and build the associated internal data structures. It does the checking of the input XML up to making sure all the needed informations are availble in the right place, but does not check for extra data. It should support the full format as defined by interface.rng as of netcf version 0.1.0, both for input and output. This is rather repetitive and boring code, so I tried to factorize things following patterms similar to the one used in the grammar, the code reflects to a large extent the definition blocks there. The main data structure is virInterfaceDef, it defines the most common and shared attributes of all interfaces, the protocol definition allowed in the schemas is only ipv4 at the moment but with the expected extension to allow ipv6 in parallel I made a separate structure (currently embedded in the main one). There is a enum discriminating the specific structures needed for vlan, bride and bonding, and for the two last ones, a dynamically allocated array of bare interfaces (which can be of vlan or ethernet type, merged into a single structure). This passes valgrind, but since I'm not testing agaisnt misformed XML input I afraid of potential leaks on exit paths, otherwise this should be fine.
