linear hash implementation. In particular, I've implemented (sort of) an iterator for linear hash, and (sort of) ported libdfa to linearhash.c I say 'sort of' since this functionality is broken with this commit. On the other hand, CVS should build now, and the tests under lladd will pass. libdfa's new tests don't pass at the moment.
