This patch changes the module biuld so that stateful drivers like QEMU
and LXC are directly linked into the libvirtd daemon, and not part of the
libvirt.so file. It also does this for network and storage drivers. We
need to export a few more symbols for this to work, and libvirtd has to
explicitly initialize these drivers. Thanks to the previous patch changing
the probe method, automatic driver probing still works.
