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.

Eric Blake ca92c85756 virsh: improve option handling
The documentation for vshCommandOptString claims that it returns
-1 on a missing required argument, but in reality, that error
message was unreachable (it was buried inside an if clause that
is true only if the argument was present).  The code was so hairy
that I decided a rewrite would make it easier to understand,
and actually return the error values we want.

Meanwhile, our construction guarantees that all vshCmdOpt have
a non-null def member, so there are some redundant checks that
can be trimmed.

* tools/virsh.c (vshCommandOpt): Alter signature.
(vshCommandOptInt, vshCommandOptUInt, vshCommandOptUL)
(vshCommandOptString, vshCommandOptLongLong)
(vshCommandOptULongLong, vshCommandOptBool): Adjust all callers.
(vshCommandOptArgv): Remove dead condition.

         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.
