This CL fixes following test cases in minikin_tests - FontFamilyTest.hasVariationSelectorTest - HbFontCacheTest.getHbFontLockedTest - HbFontCacheTest.purgeCacheTest For the fix of FontFamilyTest.hasVariationSelectorTest, removing virtual from GetUniqueId() in MinikinFont. After [1], MinikinFont's destructor started calling purgeHbCache() which calls virtual method, MinikinFont::GetUniqueId(). Fortunately, the SkTypeface::uniqueID() returns just internal value, so we can store it at the construction time and use it instead of calling SkTypeface::uniqueID() every time. This patch also changes purgeHbFont to purgeHbFontLocked, as all uses of it were already under global mutex. This change avoids deadlock on explicit unref, as when invoked by a Java finalizer from the Java object that holds a reference to the font. Some of the tests needed to change to using the ref counting protocol rather than explicitly destructing font objects, as well.
