Use funopen() instead of fdopen(). This fixes three problems:
Use funopen() instead of fdopen(). This fixes three problems:

 - ftpTimeout was not honored when reading actual data, as opposed to
   talking protocol

 - connection caching was broken because _ftp_cached_connect() would see
   the result of the transfer instead of the result of the NOOP.

 - if the RETR succeeded, but an error occurred later (as can happen
   when talking to a proxy), the error would not be detected.

There still remains to register an atexit(3) callback to close the cached
connection gracefully instead of just dropping it on the floor.
