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the issues currently addressed in the memory-leaks branch are superseded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.

function Rho = lshRho(w,c)
if nargin<2, c=1;end
if nargin<1, w=4;end

P1 = lshP(w,1);
P2 = lshP(w,c);

Rho = log(1./P1) ./ log(1./P2);
