Renamed the curl_ftpssl enum to curl_usessl and its enumerated constants,
creating macros for backward compatibility.

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.

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

2) added nroff header

 * #undef CURL_FTP_HTTPSTYLE_HEAD in lib/ftp.c to remove the HTTP-style headers
   from being output in NOBODY requests over ftp

the configure script checks for openldap and friends and we link with those
libs just like we link all other third party libraries, and we no longer
dlopen() those libraries. Our private header file lib/ldap.h was renamed to
lib/curl_ldap.h due to this. I set a tag in CVS (curl-7_17_0-preldapfix)
just before this commit, just in case.

the multi interface, but having the comment in here caused more questions than
we fixed problems so I remove it now. It still works fine.

Peteris Krumins pointed out that MingW32 doesnt provide a batch file to set the path to the bin folder.

some brief hints about gssapi and libssh2

passed to it with curl_easy_setopt()! Previously it has always just refered
to the data, forcing the user to keep the data around until libcurl is done
with it. That is now history and libcurl will instead clone the given
strings and keep private copies.

when using the socket API

lower case for consistency since sftp commands are case insensitive.

  getaddrinfo() sorts the response list which effectively kills how libcurl
  deals with round-robin DNS entries. All details:
