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.

   A C-program for MT19937, with initialization improved 2002/1/26.
   Coded by Takuji Nishimura and Makoto Matsumoto.

   Before using, initialize the state by using init_genrand(seed)  
   or init_by_array(init_key, key_length).
