Issue detected by Guenter Knauf's NetWare autobuild.

Moved 144 to 7.18.3 instead

  the curl_multi_socket() API with HTTP pipelining enabled and could lead to
  the pipeline basically stalling for a very long period of time until it took
  off again.

  provided excellent repeat recipes. I fixed the cases I managed to reproduce
  but Jeff still got some (SCP) problems even after these fixes:

due to KfW's library header files exporting symbols/macros that should be
kept private to the KfW library. See ticket #5601 at http://krbdev.mit.edu/rt/

  how the HTTP redirect following code didn't properly follow to a new URL if
  the new url was but a query string such as "Location: ?moo=foo". Test case
  1031 was added to verify this fix.
