Change iterator to a set of generators
Not only is the faster than a classical iterator (though still not as
fast as a while loop), but it also offers the choice of characters
or code points.

Make the iterator iterate over code points rather than characters
Also fix performance measurement for the iterator; it was all wrong.

Remove functional interface
The maintenance burden is not worth the advantages it provides in
limited situations.
Moreover, if other decoders are to be implemented, most multi-byte
schemes would not be able to support a functional interface of similar
simplicity, and single-byte schemes wouldn't benefit much

Make performance comparison fairer
The Intl tests avoided one mission user-function calls by doing a simple
loop, something unlikely to be used in real-world situations; wrapping
the test in a generator adds the overhead one would expect to have,
making the pure PHP implementation much more competitive

Correct deficiencies in UTF-8 handling
Function now operates as defined by the WHATWG encoding standard; the practical implications of this are that:
- More invalid sequences are correctly identified as invalid
- Overlong encodings are normalized
- ord() and chr() functions have been added as a consequence of this work
