Don't assume minusSign is a single char.
Locales like arabic have a multi char minusSign in
their locale data.
The only difficulty here is presented by DecimalFormatSymbols,
which is a public API and expects the minus sign to be
a single codepoint. The API has been changed to return the
first character of the minusSign string for getMinusSign, which
seems like the least bad option at this point.
This change also removes a workaround for cases where ICU
parsed (2445-) as (-2445) for RTL locales. ICU-52 doesn't do
this anymore.
The serialized form hasn't been modified either, since it's
public API as well and it isn't easy to expand to a String
without awkward semantics.
