Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
  for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
  and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
  All _VAR_ flavors changes to _DATA to be absolutely clear.
  Thank you Greg, for the most obvious suggestion.
