Begin removing uses of audiodb_query()

audiodb_query() is actually an unsupportable interface.  It requires
access to the filesystem, does not (and cannot) actually support whole
swathes of functionality, is only implementable using code that is no
longer part of the core of audioDB (reporter.h), is in the way of fixing
memory leaks in the SOAP server, and is horrible to use to boot.

So, begin converting the libtests uses of audiodb_query() to
audio_query_spec().  In the process, go through the test code and
remove useless comments, pointless variables, and commented-out bits
of shell scripts.
