so do the data->reqdata.current_conn assignment when we know there is an easy
handle existing! Fixes the valgrind report on test 509.

was even mentioned to be bad in a comment! Should make test 2000 and 2001 work
fine.

Also, freedirs() now take a ftp_conn struct pointer which saves some extra
unnecessary variable assignments.

versions of ws2tcpip.h do not have the definition. It seems that when
the socklen_t definition is missing from ws2tcpip.h the definition for
INET_ADDRSTRLEN is also missing, and that when one definition is present
the other one also is available.

that libcurl tried to re-use connections a bit too much when using non-SSL
protocols tunneled over a HTTP proxy.

https://bugzilla.novell.com/show_bug.cgi?id=332917 about a HTTP redirect to
FTP that caused memory havoc. His work together with my efforts created two
fixes:

#1 - FTP::file was moved to struct ftp_conn, because is has to be dealt with
     at connection cleanup, at which time the struct HandleData could be
     used by another connection.
     Also, the unused char *urlpath member is removed from struct FTP.

#2 - provide a Curl_reset_reqproto() function that frees
     data->reqdata.proto.* on connection setup if needed (that is if the
     SessionHandle was used by a different connection).

that specifying a proxy with a trailing slash didn't work (unless it also
contained a port number).

when assigning a NULL pointer to a function pointer var.

failure condition: http://curl.haxx.se/mail/lib-2007-10/0152.html

when assigning a NULL pointer to a function pointer var.

CURLOPT_COPYPOSTFIELDS option added for dynamic.
Fix some OS400 features.

Fixed a typo in the LDAP configure code and made sure NULL is defined
in a test programs that need it.

in the connectdata structure by a single handler table ptr.

added check for MSVC6 standard PSDK and bail out since insufficient for LDAP support with current code.

a response that was larger than 16KB is now improved slightly so that now
the restriction at 16KB is for the headers only and it should be a rare
situation where the response-headers exceed 16KB. Thus, I consider #47 fixed
and the header limitation is now known as known bug #48.

string: "FLUSH". Using that will cause libcurl to flush its cookies to the
CURLOPT_COOKIEJAR file.

This happened because the tftp code always uncondionally did a bind()
without caring if one already had been done and then it failed. I wrote a
test case (1009) to verify this, but it is a bit error-prone since it will
have to pick a fixed local port number and since the tests are run on so
many different hosts in different situations I add it in disabled state.

warnings, one C99 thing and the bad pointer sent to the callback
