Merge api-inversion branch (-r656:771, but I don't expect to return to
that branch) into the trunk.

I expect there to be minor performance regressions (e.g. in the SOAP
server index cacheing, which I have forcibly removed) and minor
unplugged memory leaks (e.g. in audioDB::query(), where I don't free up
the datum).  I hope that these leaks and performance regressions can be
plugged in short order.  I also expect that some (but maybe not all) of
the issues currently addressed in the memory-leaks branch are superseded
or fixed by this merge.

There remains much work to be done; go forth and do it.
