blockjob: implement shallow commit flag in qemu
Now that we can crawl the chain of backing files, we can do argument validation and implement the 'shallow' flag. In testing this, I discovered that it can be handy to pass the shallow flag and an explicit base, as a means of validating that the base is indeed the file we expected. * src/qemu/qemu_driver.c (qemuDomainBlockCommit): Crawl through chain to implement shallow flag. * src/libvirt.c (virDomainBlockCommit): Relax API.

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.
