Add's Java 6's DecimalFormat.setRoundingMode (et cetera).

Format and NumberFormat's bogusly-public constructors became protected with
Java 6. DecimalFormat gained more control over rounding behavior. There's a
slight mismatch with our ICU4C-based implementation in that ICU4C doesn't
support RoundingMode.UNNECESSARY, so I've had to fake that (but I doubt it's
used much, if at all).

I've pulled out the obviously Android-specific tests from the harmony
DecimalFormatTest.java, but I've only brought back the rounding mode changes
from the current harmony code to avoid the new tests' dependencies. I've also
added one new test of my own, to check that setMaximumFractionDigits affects
rounding as it should (since the harmony tests don't test this, and it's
somewhat subtle).
