More libtests fixups.

Include audiodb_close() calls everywhere (whoops).

Add the facility to run tests under valgrind.  Unfortunately the
error-exitcode flag doesn't actually cause an error exit if the only
thing wrong is memory leaks, but it will if there are actual memory
errors, which is a start.

function L = lshL(w,k,delta)
if nargin<3, delta=0.01;end
if nargin<2, k=10;end
if nargin<1, w=4;end

P1=lshP(w,1);
L = ceil(log(1./delta)/-log(1-P1^k));
