Renamed several libcurl error codes and options to make them more general

                                  Changelog

Dan F (30 August 2007)

- Renamed several libcurl error codes and options to make them more general

  and allow reuse by multiple protocols. Several unused error codes were

  removed.  In all cases, macros were added to preserve source (and binary)

  compatibility with the old names.  These macros are subject to removal at

  a future date, but probably not before 2009.  An application can be

  tested to see if it is using any obsolete code by compiling it with the

  CURL_NO_OLDIES macro defined.

  The following unused error codes were removed:

    CURLE_BAD_CALLING_ORDER

    CURLE_BAD_PASSWORD_ENTERED

    CURLE_FTP_CANT_RECONNECT

    CURLE_FTP_COULDNT_GET_SIZE

    CURLE_FTP_COULDNT_SET_ASCII

    CURLE_FTP_USER_PASSWORD_INCORRECT

    CURLE_FTP_WEIRD_USER_REPLY

    CURLE_FTP_WRITE_ERROR

    CURLE_LIBRARY_NOT_FOUND

    CURLE_MALFORMAT_USER

    CURLE_OBSOLETE

    CURLE_SHARE_IN_USE

    CURLE_URL_MALFORMAT_USER

  The following error codes were renamed:

    CURLE_FTP_ACCESS_DENIED =>      CURLE_REMOTE_ACCESS_DENIED

    CURLE_FTP_COULDNT_SET_BINARY => CURLE_FTP_COULDNT_SET_TYPE

    CURLE_FTP_QUOTE_ERROR =>        CURLE_QUOTE_ERROR

    CURLE_TFTP_DISKFULL =>          CURLE_REMOTE_DISK_FULL

    CURLE_TFTP_EXISTS =>            CURLE_REMOTE_FILE_EXISTS

    CURLE_HTTP_RANGE_ERROR =>       CURLE_RANGE_ERROR 

  The following options were renamed:

    CURLOPT_SSLKEYPASSWD => CURLOPT_KEYPASSWD 

    CURLOPT_FTPAPPEND =>    CURLOPT_APPEND

    CURLOPT_FTPLISTONLY =>  CURLOPT_DIRLISTONLY

    CURLOPT_FTP_SSL =>      CURLOPT_USE_SSL

  A few more changes will take place with the next SONAME bump of the

  library.  These are documented in docs/TODO

- Documented some newer error codes in libcurl-error(3)

- Some minor internal type and const changes based on a splint scan.

Daniel S (24 August 2007)

- Bug report #1779054 (http://curl.haxx.se/bug/view.cgi?id=1779054) pointed

  out that libcurl didn't deal with large responses from server commands, when

 o HTTP transfers have the download size info "available" earlier

 o FTP transfers have the download size info "available" earlier

 o builds and runs on OS/400

 o several error codes and options were marked as obsolete and subject to

   future removal (set CURL_NO_OLDIES to see if your application is using them)

This release includes the following bugfixes:

   and FTP-SSL tests without the stunnel dependency, and it could allow us to

   provide test tools built with either OpenSSL or GnuTLS

 * Make the test servers able to serve multiple running test suites. Like if

   two users run 'make test' at once.

 * If perl wasn't found by the configure script, don't attempt to run the

   tests but explain something nice why it doesn't.

 * #undef CURL_FTP_HTTPSTYLE_HEAD in lib/ftp.c to remove the HTTP-style headers

   from being output in NOBODY requests over ftp

 * Combine some of the error codes to remove duplicates.  The original

   numbering should not be changed, and the old identifiers would be

   macroed to the new ones in an CURL_NO_OLDIES section to help with

   backward compatibility.

   Candidates for removal and their replacements:

      CURLE_FILE_COULDNT_READ_FILE => CURLE_REMOTE_FILE_NOT_FOUND

      CURLE_FTP_COULDNT_RETR_FILE => CURLE_REMOTE_FILE_NOT_FOUND

      CURLE_FTP_COULDNT_USE_REST => CURLE_RANGE_ERROR

      CURLE_FUNCTION_NOT_FOUND => CURLE_FAILED_INIT

      CURLE_LDAP_INVALID_URL => CURLE_URL_MALFORMAT

      CURLE_TFTP_NOSUCHUSER => CURLE_TFTP_ILLEGAL

      CURLE_TFTP_NOTFOUND => CURLE_REMOTE_FILE_NOT_FOUND

      CURLE_TFTP_PERM => CURLE_REMOTE_ACCESS_DENIED

 NEXT MAJOR RELEASE

 * curl_easy_cleanup() returns void, but curl_multi_cleanup() returns a

			fseek(f, uploaded_len, SEEK_SET);

			curl_easy_setopt(curlhandle, CURLOPT_FTPAPPEND, 1);

			curl_easy_setopt(curlhandle, CURLOPT_APPEND, 1);

		}

		else { /* no */

			curl_easy_setopt(curlhandle, CURLOPT_FTPAPPEND, 0);

			curl_easy_setopt(curlhandle, CURLOPT_APPEND, 0);

		}

		r = curl_easy_perform(curlhandle);

      /* sorry, for engine we must set the passphrase

         (if the key has one...) */

      if (pPassphrase)

        curl_easy_setopt(curl,CURLOPT_SSLKEYPASSWD,pPassphrase);

        curl_easy_setopt(curl,CURLOPT_KEYPASSWD,pPassphrase);

      /* if we use a key stored in a crypto engine,

         we must set the key type to "ENG" */
