Fix symbol exports & remove duplicated libvirt_util.la linkage
The libvirt_util.la library was mistakenly linked into libvirtd directly. Since libvirt_util.la is already linked to libvirt.so, this resulted in libvirtd getting two copies of the code and more critically 2 copies of static global variables. Testing in turn exposed a issue with loadable modules. The gnulib replacement functions are not exported to loadable modules. Rather than trying to figure out the name sof all gnulib functions & export them, just linkage all loadable modules against libgnu.la statically. * daemon/Makefile.am: Remove linkage of libvirt_util.la and libvirt_driver.la * src/Makefile.am: Link driver modules against libgnu.la * src/libvirt.c: Don't try to load modules which were compiled out * src/libvirt_private.syms: Export all other internal symbols that are required by drivers
