Note that with this change, libicu-50.1.2-2.fc19 and libicu-50.1.2-3.fc19
has the libraries with the same sonames, but containing _different_
symbols:

# rpmsodiff libicu-50.1.2-*rpm
        common sonames:
libicudata.so.50        /usr/lib/libicudata.so.50.1.2   /usr/lib/libicudata.so.50.1.2

So packages rebuilt against icu-50.1.2-1.fc19  or icu-50.1.2-2.fc19
won't receive any errors from rpm dependency resolver if icu is
to be upgraded to icu-50.1.2-3.fc19, but they will break silently
(unless they are rebuilt against newer icu).
