Almost finish with audioDB::query_loop.

This patch is a little bit noisy, because we rename adb->keys to
adb->keymap, introduce a new vector adb->keys (essentially to replace
fileTable), and introduce new functionality (both include and exclude
keylists in adb_query_refine_t) as well as modifying the query_loop
function itself to take advantage of all of these goodies.  Oh, and we
also fix an embarrassing state bug in adb->track_offsets for insert --
what was I thinking?  (Thank you, regression test suites).  Since we are
on a private branch at the moment, we can take the luxury of renumbering
the ADB_REFINE_ flags to include the exclude list at the logical place;
once we have an ABI to support, that won't be possible.

Now audioDB::query builds up include and exclude lists as appropriate;
query_loop does an [O(NlogN) probably] buildup of the keys to consider,
and then iterates over tracks sequentially, seeking only if one or more
tracks have been excluded.  No more trackFile, yay!

The only remaining thing to deal with is the accumulator.  It's easy
enough to pass it around, but I want to read the indexed version before
doing so to see how that all fits together.
