optionally enforce serialization of pads
From now on, due to a patch in libxcb, pads will not be serialized
anymore. This is to maintain ABI-compatibility when adding
explicit align pads.
However, some align pads were already be serialized in prior
official versions of libxcb. Therefore we need a method to
enforce serialization, so we can maintainn ABI compatibility
with that legacy.
