Refactor the ICU code for QLocale

Clean up the ICU code and make it thread-safe. Add a
QIcuData structure to QLocalePrivate, that contains
ICU specific data.

Link against ICU directly, greatly simplifying the
code.

Also fix a bug in the locale specific case conversion
code that would cause it to fail and fall back to the
QString code if the output string was larger than the
input.
