Move term validation into ChangeOps

NOTE: this changes constraint checking for some cases:
* sitelink constraints are now *always* checked
* label/description uniqueness becomes a "soft" constraint,
  checked only for new input.

NOTE: this also changes how sitelink constraints are enforced
in ChangeOpsMerge. This is a side effect of consolidating
the constraint handling.
