Update java.text to Harmony r802921.

Update java.text to Harmony r802921.

Notable changes:
 - Replaced some StringBuffers with StringBuilders
 - Harmony moved to ICU, we stayed with ResourceBundles
 - Harmony now uses ICU's Bidi, we continue to use BidiWrapper
 - Fixed DateFormat.readResolve()
 - Fixed DecimalFormat serialization for setMaximumIntegerDigits
 - Fixed currency to support "XXX" for null
 - Support for null in MessageFormat.format()
 - Rearranged methods in SimpleDateFormat. Body is the same.
 - Fixed tests for Bidi.getRunLimit(). These are new failures.
