out of memory (thanks to 'runtests.pl -t')

of using 'lud_filter' after freeing 'lud_dn'.

Patch for ldap.c under Windows. It works with wldap32.dll as supplied with
Win-98/ME/2000/XP, so no extra .dlls are required.  I've mostly tested it
against Verisign's ldap server. Added code in the case there are to many
responses (rc = LDAP_SIZELIMIT_EXCEEDED) and print only those we got. E.g.

curl
ldap://directory.verisign.net/?cn,display-name,mail,info?subtree?(cn=*Nelson*)

will print the first 10 results.

My only problem with it is that ldap_search_s() fails with "filter error" when
CURLDEBUG is defined ?! Maybe someone can spot the error.

curlx_ functions are NOT part of the offical API, but only available as source
code functions from the lib directory in case of need.

work when using proxy by converting the IDN-name to the ACE-encoded version
before the request-URL is passed to the proxy.

and then figure it out with a suitable windows call.

all things up to work with encoded host names internally, as well as keeping
'display names' to show in debug messages. IDN resolves work for me now using
ipv6, ipv4 and ares resolving. Even cookies on IDN sites seem to do right.

instead, its only for debug verbose output anyway
