(http://curl.haxx.se/bug/view.cgi?id=1776235) about ftp requests with NOBODY
on a directory would do a "SIZE (null)" request. This is now fixed and test
case 1000 was added to verify.

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

range. They are about FTP but the 100-199 range is full.

HTTP PUT using Digest authentication. Test case 5320 and 5322 were also
added to verify the functionality.

added basic ldaps support; for now its ifdef'd with HAVE_LDAP_SSL unless we know its fully working, and available with all LDAP SDKs.
Win32 requires to have the trusted CA in local keystore - I've not found yet a way to disable the cert check.

other minor makefile tweaks.

NTLMFLAG_NEGOTIATE_UNICODE, we need to filter it off because libcurl doesn't
unicode encode the strings it packs into the NTLM authenticate packet.

indented some of the code to curl-style

size earlier when doing HTTP downloads, so that applications and the
progress meter etc know get the info earlier in the flow than before.

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.

fixed warning with gcc 4.x (hopefully); dynamincally imported UseAccurateCaseForPaths() for CLIB port to be stonetime-compatible (NW 3.x).

countermeasures code path.

Improve "universal" alignment type in struct memdebug

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.

undef standard *printf before (re)defining them
