[libvirt] [PATCH 3/6] unpriv_sgio: Prepare helpers for unpriv_sgio setting

[Osier Yang]

"virGetDevice{Major,Minor}" could be used across the sources,
but it doesn't relate with this series, and could be done later.

* src/util/util.h: (Declare virGetDevice{Major,Minor}, and
                    vir{Get,Set}DeviceUnprivSGIO)
* src/util/util.c: (Implement virGetDevice{Major,Minor} and
                    vir{Get,Set}DeviceUnprivSGIO)
* src/libvirt_private.syms: Export private symbols of upper helpers
