Re: [libvirt] [PATCH 1/2] build: define WITH_INTERFACE for the driver

Based exclusively on work by Eric Blake in a patch posted with the same subject. However some modifications related to comments and my plans to add another backend. Added WITH_INTERFACE as the only automake variable deciding whether to build the driver and using WITH_NETCF to identify that we're wanting to use the netcf library as the backend. * configure.ac: Added with_interface * src/interface/netcf_driver.c: Renamed.. * src/interface/interface_backend_netcf.c: ..to this to match storage. * src/interface/netcf_driver.h: Renamed.. * src/interface/interface_driver.h: ..to this. * daemon/Makefile.am: Respect WITH_INTERFACE and WITH_NETCF.
