Summary

Replace usages of the internal sun.util.locale.ParseStatus class with java.text.ParsePosition.

Problem

ParseStatus has almost 1 to 1 behavior with ParsePosition. We can get rid of the internal class by making the switch.

Solution

Replace usages of the internal class with java.text.ParsePosition. Remove the sun.util.locale.ParseStatus.

As a byproduct of this switch, the exception message for Locale.caseFoldLanguageTag(String) is updated to no longer be prepended with "Ill formed tag: ". This change should be okay, as the rest of the message contains sufficient detail. It is also clear the tag is ill formed, as the holder exception is an IllFormedLocaleException.

Note that while this cleanup/switch itself is compatibility friendly, this CSR is filed solely to address the changed exception message.
