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).

#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);
}
