build: avoid infinite autogen loop
Several people have reported that if the .gnulib submodule is dirty, then 'make' will go into an infinite loop attempting to rerun bootstrap, because that never cleans up the dirty submodule. By default, we should halt and make the user investigate, but if the user doesn't know why or care that the submodule is dirty, I also added the ability to 'make CLEAN_SUBMODULE=1' to get things going again. Also, while testing this, I noticed that when a submodule update was needed, 'make' would first run autoreconf, then bootstrap (which reruns autoreconf); adding a strategic dependency allows for less work. * .gnulib: Update to latest, for maint.mk improvements. * cfg.mk (_autogen): Also hook maint.mk, to run before autoreconf. * autogen.sh (bootstrap): Refuse to run if gnulib is dirty, unless user requests discarding gnulib changes. (cherry picked from commit c5f162200c32a078fd68507f26a15f84f7d65e9e)
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
