in libcurl as well, if necessary.

DNS cache must use the multi DNS cache if the easy handle's one is not using anyone in curl_multi_add_handle.

string comparisons on the path which is incorrect and provided a patch that
fixes this. I edited test case 8 to include details that test for this.

the crash was that libcurl internally was a bit confused about who owned the
DNS cache at all times so if you created an easy handle that uses a shared
DNS cache and added that to a multi handle it would crash. Now we keep more
careful internal track of exactly what kind of DNS cache each easy handle
uses: None, Private (allocated for and used only by this single handle),
Shared (points to a cache held by a shared object), Global (points to the
global cache) or Multi (points to the cache within the multi handle that is
automatically shared between all easy handles that are added with private
caches).

Prevent definition of HAVE_WINxxx_H symbols and avoid inclusion of Windows headers when compiled with Cygwin in POSIX emulation mode.

So avoid using x_was_used().

(serialise) a previously built formpost (as with curl_formadd()).

curl_socket_t is unsigned (like Windows) that could cause it to wrongly
return a max fd of -1.

CURLOPT_MAX_RECV_SPEED_LARGE that limit tha maximum rate libcurl is allowed
to send or receive data. This kind of adds the the command line tool's
option --limit-rate to the library.

The rate limiting logic in the curl app is now removed and is instead
provided by libcurl itself. Transfer rate limiting will now also work for -d
and -F, which it didn't before.
