Begin pushing information through.

Create and initialize an adb_query_refine_t struct in audioDB::query,
and pass it through to various callees, which can then use it instead of
the automagic class member variables.

This allows conversion of some routines into ordinary static C
functions.  Begin doing so.

#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);
}
