begin work on sampling API

This is motivated by the need to be able to sample with arbitrary feature data
(e.g. from a feature file) against a database, for the JNMR "collections" paper
revisions or possible ISMIR paper revisions.  That bit doesn't work yet, but
the C-ified version of the current functionality (sample db x db and
sample key x db) works to the level of anecdotal tests.

The general approach is to mirror the _query_spec() API, where a whole heap
of knobs and twiddles are available to the user.  Unlike in the _query_spec()
API, not quite all of the knobs make sense (and even fewer are actually
implemented), but the basic idea is the same.

I pity the poor chump who will have to document all this.

#include "audioDB_API.h"
#include "test_utils_lib.h"

int main(int argc, char **argv) {
  adb_t *adb;
  struct stat st;

  clean_remove_db(TESTDB);

  adb = audiodb_open(TESTDB, O_RDWR);
  if(adb)
    return 1;

  adb = audiodb_create(TESTDB, 0, 0, 0);
  if (!adb)
    return 1;

  if(stat(TESTDB, &st))
    return 1;

  audiodb_close(adb);

  adb = audiodb_create(TESTDB, 0, 0, 0);
  if(adb)
    return 1;

  adb = audiodb_open(TESTDB, O_RDONLY);
  if (!adb)
    return 1;

  audiodb_close(adb);

  return 104;
}
