interface: Make _virInterfaceObjList struct private

Browse Source 
Move the structs into virinterfaceobj.c, create necessary accessors, and
initializers.

This also includes reworking virInterfaceObjListClone to handle receiving
a source interfaces list pointer, creating the destination interfaces object,
and copying everything from source into dest.
