Eric Blake 4199f3de2e API: prevent query of --live and --config at once 
Drivers were inconsistent when presented both --live and --config
at once.  For example, within qemu, getting memory parameters
favored live, getting blkio tuning favored config, and getting
scheduler parameters errored out.  Also, some, but not all,
attempts to mix flags on query were filtered at the virsh level.
We shouldn't have to duplicate efforts in every client app, nor
in every driver.  So, it is simpler to just enforce that the two
flags cannot both be used at once on query operations, which has
precedent in libvirt.c, and which matches the documentation of
virDomainModificationImpact.

* src/libvirt.c (virDomainGetMemoryParameters)
(virDomainGetBlkioParameters)
(virDomainGetSchedulerParametersFlags, virDomainGetVcpuPinInfo):
Borrow sanity checking from virDomainGetVcpusFlags.

         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.
