- Bug report #651460 by Christopher R. Palmer showed that when using libcurl

  to for example go over a proxy on localhost, it would attempt to connect

  through the proxy TWICE.

  I added test case 503 with which I managed to repeat this problem and I

  fixed the code to not re-attempt any connects (which also made it a nicer

  fix for the #650941 bug mentioned below).

  The sws server was extended to deal with CONNECT in order to make test

  case 503 do good.

- Evan Jordan posted bug report #650989 about a memory leak in the public key

  retrieving code. He provided a suggested fix and I merely applied it!

- Bug report #650941, posted by Christopher R. Palmer identified a problem

  with the multi interface and getting file:// URLs. This was now fixed and

  test case 502 was added to verify this.

- Test case 500 and 501 are the first ever libcurl test cases that run.

- Made "configure --enable-debug" cut off all -O* options to the compiler

- Finally fixed the test suite's ftp server so that test case 402 doesn't

  cause the following test case to fail anymore!

- CURL_MAX_WRITE_SIZE is now decreased to 16KB since it makes the Windows

  version perform uploads much faster!!!

- Fixed the #include in curl/curl.h to include the other files outside the

  extern "C" scope.

- Moved around and added more logic:

  First, POST data is never sent as part of the request headers in the http.c

  code. It is always sent the "normal" read callback then send() way. This now
