Re: [libvirt] [PATCH v1 2/3] qemu_conf.c: introduce qemuAddRemoveSharedDiskInternal

Following the same idea of avoid code repetition from the previous patch, this commit introduces a new function that aggregates the functions of qemuAddSharedDisk() and qemuRemoveSharedDisk() into a single place, using a flag to switch between add/remove operations. Both qemuAddSharedDisk() and qemuRemoveSharedDisk() are public, so keep them around to avoid changing other files due to an internal qemu_conf.c refactory. No functional change was made.
