No more global shingle vector of vectors.

Convert audioDB::index_initialize_shingles and
audioDB::index_norm_shingles to plain old functions.  In doing so, the
latter in particular acquires a silly argument list; we need that
complexity for now because it's called both from audioDB::query (which
we're currently inverting) and from audioDB::index (which is out of
scope for now).

The loss of the global vv thing made me check up on memory discipline
[hence the new API function audiodb_query_free_results() as well as the
internal audiodb_index_delete_shingles()].  It's not too bad, but there
are plenty of leaks for those with time to do
  AUDIODB="valgrind --leak-check=full ../../audioDB" sh ./run-test.sh
on their favourite test case.  For example, the Radius reporters leak
one triple per hit.

(Honestly, C++ memory management is teh suck.)
