the new ftp code and Gisle's DICT fix

                                  Changelog

- Converted lots of FTP code to a statemachine, so that the multi interface

  doesn't block while communicating commands-responses with an FTP server.

  I've added a comment like BLOCKING in the code on all spots I could find

  where we still have blocking operations. When we change curl_easy_perform()

  to use the multi interface, we'll also be able to simplify the code since

  there will only be one "internal interface".

  While doing this, I've now made CURLE_FTP_ACCESS_DENIED separate from the

  new CURLE_LOGIN_DENIED. The first one is now access denied to a function,

  like changing directory or retrieving a file, while the second means that we

  were denied login.

  The CVS tag 'before_ftp_statemachine' was set just before this went in, in

  case of future need.

- Gisle made the DICT code send CRLF and not just LF as the spec says so.

- Gisle fixed problems when libcurl runs out of memory, and worked on making

  sure the proper error code is returned for those occations.
