Begin working towards inverting audioDB::insert() / audiodb_insert().

New data type audiodb_datum_t, roughly corresponding to a "track" in
current audioDB parlance; it contains exactly the feature information
and metadata to record.

New function audiodb_insert_datum() to insert one of these
audiodb_datum_t objects into the database; the intention is that not
only can insertion of feature files be implemented in terms of this
function, but that it will be a useful function in its own right,
callable perhaps from PD, Max/MSP, and/or a VAMP plugin.  This function
is complicated enough that it actually gets a comment.

Implement audioDB::insert() in terms of audiodb_insert_datum(), via a
wrapper which handles the slightly wacky error/non-error case of
attempting to insert features with a key that already exists in the
database.

Delete whole rafts of code.  We can't quite delete everything because
there's batchinsert / batchinsert_large_adb to sort out; the good news
is that the batchinsert operation can simply be implemented as a loop
around audiodb_insert_datum() without loss of efficiency.

(There's also a stray extra audiodb_insert() in libtests/0027/, found
through an earlier iteration of this patch.)
