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.

#! /bin/bash

. ../test-utils.sh

if [ -f testdb ]; then rm -f testdb; fi

${AUDIODB} -d testdb -N

# tests that the lack of -l when the query sequence is shorter doesn't
# segfault.

intstring 2 > testfeature
floatstring 0 1 >> testfeature
floatstring 1 0 >> testfeature

${AUDIODB} -d testdb -I -f testfeature

# sequence queries require L2NORM
${AUDIODB} -d testdb -L

echo "query point (0.0,0.5)"
intstring 2 > testquery
floatstring 0 0.5 >> testquery

expect_clean_error_exit ${AUDIODB} -d testdb -Q sequence -f testquery
expect_clean_error_exit ${AUDIODB} -d testdb -Q sequence -f testquery -n 1

echo "query point (0.5,0.0)"
intstring 2 > testquery
floatstring 0.5 0 >> testquery

expect_clean_error_exit ${AUDIODB} -d testdb -Q sequence -f testquery
expect_clean_error_exit ${AUDIODB} -d testdb -Q sequence -f testquery -n 1

exit 104
