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

CURLOPT_OPENSOCKETDATA to set a callback that allows an application to replace
the socket() call used by libcurl. It basically allows the app to change
address, protocol or whatever of the socket. (I also did some whitespace
indent/cleanups in lib/url.c which kind of hides some of these changes, sorry
for mixing those in.)
