Fix harmony java.text test failures.
There were plenty of bad tests here, but there were some real bugs too.
* DecimalFormat was only handling RoundingMode.UNNECESSARY for double
formatting.
* DecimalFormat was not ensuring that it's superclass' fields were
being correctly updated.
* NumberFormat was throwing NPE for a null object because of an
improved detail message, despite being specified to throw IAE.
* We weren't mapping NumberFormat.Field instances to the corresponding icu4c
UNUM_x_FIELD constant, so we weren't actually setting FieldPosition
objects correctly.
* SimpleDateFormat was not formatting milliseconds correctly with 'S'.
* NativeDecimalFormat wasn't handling JNI NewString OOME correctly.
