SkUTF8_CountUnichars(s,l) and SkUTF8_NextUnichar(s,l) now safe.

Theory:  We will accept blobs of data as utf-8 text without validation,
but when it comes time to process it: count code poits or convert to
code points, be careful to check for errors.

TODO: SkTypeface::charsToGlyphs() needs to take a length.
