Implement a rudimentary API for audioDB::liszt

The API is rudimentary because we've dropped support for the incremental
retrieval of tracks and their number of vectors (at the API level; the
SOAP and command-line support is still there -- no changes should be
visible).  This is potentially bad for the large-scale databases, of
course; one million tracks will take of the order of 16MB of RAM, more
if I'm unlucky about how std::string.c_str() is implemented.

Both this liszt operation and querying (and sampling, forthcoming...)
would benefit from a `cursor-like' interface to retrieval results: for
an API like that, instead of getting a struct with the data there, you
get a cookie with which you can ask the database for successive results.
This would be neat for all sorts of reasons.  In the meantime, at least
this change fixes SOAP memory leaks related to liszt.

Make liszt.o part of LIBOBJS rather than ordinary OBJS, so that the
liszt functionality is actually compiled into the library.

Add a test for this library functionality; also modify the command-line
test file to run the SOAP server on its own port.

# NB: one might be tempted to insert a test here for having both keys
# in the keylist, but in non-database order, and then checking that
# the result list is also in that non-database order.  I think that
# would be misguided, as the efficient way of dealing with such a
# keylist is to advance as-sequentially-as-possible through the
# database; it just so happens that our current implementation is not
# so smart.
