After sleeping over it, I've been able to come up with a split of the
patches for v17 and HEAD: a first one to refactor the 2PC code to
integrate more FullTransactionIds (down to 17) and a second one to
implement a fix.  That should make reviews easier.  The second patch
for 17 and HEAD matches with the fixes for v13~v16, all are labelled
with a 0002.
