New (internal) function audiodb_query_spec_qpointers()

Intended to replace audioDB::set_up_query and
audioDB::set_up_query_from_key; it isn't yet called, but I want to save
my work now before messing with stuff, because the function itself is
long and complicated: it handles three separate ways of getting data
together (datum provided, key provided + LARGE_ADB, key provided +
!LARGE_ADB).

There is insufficient error checking as yet, but hey.

#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);
}
