Enforce consistent sizes for arrays in SpannableStringInternal
The grow logic in SpannableStringInternal#setSpan assumes that the
size of mSpanData is consistent with that of mSpans, in particular
that if the latter doesn't need to grow, neither does the former.
The copySpans() method didn't enforce this, creating an mSpanData
array only big enough to hold the data.
This patch documents the invariant in a comment and enforces it.
