Subject: Add a new static function LLFile::size() to determine the size of a
 file_name. Replace LLAPRFile::remove(), LLAPRFile::size() and
 LLAPRFile::isExist() with according functions from LLFile and retire these
 LLAPRFile methods and the never used LLAPRFile::rename(),
 LLAPRFile::makeDir() and LLAPRFile::removeDir() functions. Also clean up
 remarks about the threading safety of the APRCachePool, which is not used in
 these locations anymore.
