Slight rearrangement of insert code.

Move most of audiodb_insert() into a helper function to create an
adb_datum_t from an adb_insert_t.  (Most of the rest of it goes into
another helper function for cleaning up).

Now audiodb_insert() is small enough that it's plausible to move the
O2_FLAG_LARGE_ADB into it from audioDB::insert.  The plan is to add
support for the LARGE_ADB case in audiodb_insert(), at which point
audiodb_batchinsert() will Just Work, and we'll be able to delete
audioDB::batchinsert_large_adb (which is good, because it's an
almost-but-not-quite-identical copy of audioDB::batchinsert).
