The current qemu capabilities are stored in a virBitmapPtr object, whose type is exposed to callers. We want to store more data besides just the flags, so we need to move to a struct type. This object will also need to be reference counted, since we'll be maintaining a cache of data per binary. This change introduces a 'qemuCapsPtr' virObject class. Most of the change is just renaming types and variables in all the callers Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
