        * configure.ac:
        + macros/check.m4: add support for using check for unit tests, the .m4
        files is so autogen can run without check being installed

        * tests/Makefile.am:
        + tests/test-rhythmdb.c: update the tests to new rhythmdb API, port
        some of the old tests, and add some new ones. Currently
        deserialisation tests 2 and 3 fail, for reasons I haven't figured out
        yet (the query doesn't return any entries).

        - tests/deserialization-test1.xml:
        - tests/deserialization-test2.xml:
        - tests/deserialization-test3.xml:
        - tests/test-rhythmdb-indexing.c:
        - tests/test-rhythmdb-simple.c:
        - tests/test-rhythmdb-tree-deserialization.c: remove old tests that
        have been ported

        - tests/test-cd.c:
        - tests/test-cmdline.c: remove obsolete tests
