[libvirt] [PATCHv2 02/14] vcpu: add new public API



API agreed on in
https://www.redhat.com/archives/libvir-list/2010-September/msg00456.html

v2: update enum names for consistency with virDomainDeviceModifyFlags.

* include/libvirt/libvirt.h.in (virDomainVcpuFlags)
(virDomainSetVcpusFlags, virDomainGetVcpusFlags): New
declarations.
* src/libvirt_public.syms: Export new symbols.
