Convert index-finding logic to C functions.

New audiodb_index_exists() and audiodb_index_get_name().  The behaviours
of the functions are unchanged, even though they are kind of weird; in
particular, passing in a buffer rather than returning a char * for
audiodb_index_get_name() is probably likely to work better eventually
(see the changes to soap.cpp, which show a clear leak of a buffer in the
error case)

#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);
}
