[debugging]

It turns out that it's mainly the IPV6 stuff that fails. The first stopblock
was an obvious error in the call to getaddrinfo(), the second parameter is
(char*)"0" It should be NULL (although (char*)0 would work too, i.e. no ""),
ref. Linux manpage (the AIX manpage says the same thing):

       int getaddrinfo(const char *node, const char *service,
..
       The node or service parameter, but not both, may be NULL.

Fixing that got me past the getaddrinfo() call (see patch at the end), but
there are still problems further down in the ftp_use_port() function, possibly
because of problems with some of the return values from both getaddrinfo()
and other calls.
I'm not sure if IPV6 on AIX has bugs, I'll debug this further when I'll
get a bit more time available.

Compiling withouth ipv6 got rid of most of the AIX problems, the rest were
SSL tests (300 301 304 306).
I've uploaded more testsets (http://curl.haxx.se/auto/), without ipv6 as
well as withouth ssl.
