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.

#include "audioDB_API.h"

int main(int argc, char **argv) {
  adb_t *adb;
  
  clean_remove_db(TESTDB);
  if(!(adb = audiodb_create(TESTDB, 0, 0, 0)))
    return 1;

  if(audiodb_power(adb))
    return 1;
  if(audiodb_power(adb))
    return 1;

  audiodb_close(adb);

  return 104;
