No, you can leave HEAD alone --- renumbering the enum values in
master is fine, since we force extensions to recompile against
new major versions. We just need to hold the values steady in
released branches.
Personally I'd keep SO_TYPE_TIDSCAN physically adjacent to the other
SO_TYPE_xxxSCAN entries in the list, but of course that's just cosmetic.
