Tighten definition of regular expression iterators so they are noexcept and

define all the standard member functions. This cascades to all methods called
by the iterators, affecting Document, CellBuffer, Partitioning, SplitVector and
UTF-8 and DBCS functions.
Other trivial functions declared noexcept.
