dictates a CJK rune is only part of a certain specified range if it
is explicitly defined in the Unicode Codepoint Database.
Fixed the code and some of the tests accordingly.

The first bug was that tertiary ignorables had the same colElem as
implicit colElems, yielding unexpected results. The current encoding
ensures that a non-implicit colElem is never 0. This fix uncovered
another bug of the trie that indexed incorrectly into the null block.
This was caused by an unfinished optimization that would avoid the
need to max out the most-significant bits of continuation bytes.
This bug was also present in the trie used in exp/norm and has been
fixed there as well. The appearence of the bug was rare, as the lower
blocks happened to be nearly nil.

context for change lists of lower-level types. The public APIs are defined
in builder.go and collate.go. Type table is the glue between the lower and
higher level code and might be a good starting point for understanding the
collation code.

The trie code looks a lot like the trie in exp/norm. It uses different
types, however. Also, there is only a lookup for []byte and the unsafe
lookup methods have been dropped, as well as sparse mode.
There is now a method for generating a trie. To output Go code, one now needs
to first generate a trie and then call print() on it.
