Patchset pushed to https://github.com/jbellis/cassandra/tree/5403.  (To save me rebase pain,
it builds on the patches for CASSANDRA-5395, which are not yet committed, but you don't need
to re-review those.  So the first commit to review here is 20ebbe37867820e83f0fef63f95fc0cb9e7982ea:
make getColumnNames return Iterable.)

> CF wraps ISC but adds no real functionality of its own (post-supercolumn cleanup).
> This means that we're wasting allocations every time we create a CF/ISC pair when really
one would do.
> Other things that would be nice to clean up:
> # We often create an empty CF as a placeholder that should not be modified, and rely
on convention to avoid such modification.  We could enforce this with a new CF/ISC subclass.
> # Many places still use TMBSC where ABSC would be adequate and cheaper
> # Other places still (ModificationStatement; others?) would be fine using a column container
with no sorting requirement at all
