Disable valgrind in test case 1004 due to a libtool bug.

Tests 35, 544 545 added: binary data POSTs.

to running it and ignoring its output).

lib is built shared with libtool.

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

Added test cases 2002 and 2003 (the latter disabled for now)

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.

Fixed the filecheck: make target to work outside the source tree

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.

accordingly.

that libcurl tried to re-use connections a bit too much when using non-SSL

105 - "invalid free after an http redirect to ftp"

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).

way:

93 - Digest for IIS fix (subject for removal)
100 - icc segmentation faults (subject for removal)

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.

In CURL_CHECK_LIBS_WINLDAP and CURL_CHECK_LIBS_LDAP, check first with no
additional library even when the optional list of libraries has been given.

Specifically for linux x86-64 with Intel's icc.
