* Throw UnsupportedOperationException for "unsanctioned units"

  call fParent.processQuantity
* toSkeleton not supported for not-built-in units
* Add and use interface
  LongNameMultiplexer.ParentlessMicroPropsGenerator
* Match up C++ and Java unit tests in NumberFormatterApiTest.java
* Permit user-override of precision() for usage(), closes icu-units#95
* Use BogusRounder to propagate mathContext.
* Port C++ change from PR #1322, commit c84ded050a, to Java.
