clarify audiodb_insert()

write audiodb_insert() (essentially to support the command-line client
audioDB::insert operation) in terms of audiodb_insert_datum() and a new
audiodb_insert_reference() function.  These two functions each do
exactly one thing and return failure if they're working on the wrong
kind of database.

#include "audioDB.h"
extern "C" {
#include "audioDB_API.h"
#include "audioDB-internals.h"
}

int audiodb_power(adb_t *adb) {
  if(!(adb->flags & O_RDWR)) {
    return 1;
  }
  if(adb->header->length > 0) {
    return 1;
  }

  adb->header->flags |= O2_FLAG_POWER;
  return audiodb_sync_header(adb);
}
