"Renaming" means the icu namespace is suffixed with the version number, atm icu_55. Using "renaming" allows to use two different versions of ICU, thus easing upgrades. For instance haikuwebkit uses a current version of ICU, while the system uses a newer one after an upgrade. * Replace all uses of the icu namespace in our public headers, with a macro defaulting to icu. As the namespace is only used for private fields pointers, there should be no impact. * Locale kit *.cpp have to import the macro from <unicode/uversion.h> *before* including any locale headers. Ditto for a Time preferences cpp file. This way, the correct current icu namespace is referenced. * Fixes bug #12057.
