invert audioDB::insert / audiodb_insert(). Start off by removing audioDB::insertDatum, and essentially reusing it as audiodb_insert. We now ignore the fact that the command-line parsing code has "helpfully" opened a std::ifstream for the times file and an fd for the power file, and simply go ahead and do our own dirty work. We can delete audioDB::insertDatum entirely, but unfortunately we can't delete audioDB::insertPowerData and audioDB::insertTimestamps, because the index and query code respectively use them. Instead, move the two methods closer to their single uses. audiodb_insert() is perhaps not as short and simple as it might have been hoped given the existence of audiodb_insert_datum(); some of that is C and its terribly way of making you pay every time you use dynamic memory; some of it is the fact that the three different files (feature, times, power) each requires slightly different treatment. Hey ho. We can implement audiodb_batchinsert() in terms of audiodb_insert(); the function is pleasingly small. We can't quite use it for audioDB::batchinsert yet, as we have to deal with the O2_FLAG_LARGE_ADB case (which codepath is untested in libtests/). This means that we can delete whole swathes of hideous code from audioDB.cpp, including not just the versions of audiodb_insert() and audiodb_batchinsert() but also an entire audioDB constructor. Yay. (audioDB::unitNormAndInsertL2 has also died a deserved death).
