c924a88e3349a27ae8b656a21e384e256f4c1e71 SkPath::shrinkToFit() needs to perform copy-on-write
When we shrink a path, we might relocate its underlying arrays.
Doing so would invalidate any outstanding Iterators. The caller must
handle this for its path object, but there may be copies elsewhere,
which have just ref'd the underlying arrays. To keep these copys'
iterators alive, we defensively "copy-on-write", so as to not relocate
their buffers.
Incidentally, update SkContourMeasureIter's constructor to clarify that
it is iterating through its copy of the path, and not the original.
