CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
  handle and uploaded another file to another directory that needed to be
  created, the second upload would fail. Another case of a state variable that
  wasn't properly reset between requests.

- I rewrote the 100-continue code to use a single state variable instead of
  the previous two ones. I think it made the logic somewhat clearer.

  (http://curl.haxx.se/bug/view.cgi?id=1911069) that identified a race

  is otherwise hard to detect abuse.

  easy handle if curl_easy_reset() was used between them. I fixed it and Brian
  verified that it cured his problem.

- Brian Ulm reported that if you first tried to download a non-existing SFTP
  file and then fetched an existing one and re-used the handle, libcurl would
  still report the second one as non-existing as well! I fixed it abd Brian
  verified that it cured his problem.

select/poll calls will only be retried upon EINTR failures as
it previously was in lib/select.c revision 1.29

In this way Curl_socket_ready() and Curl_poll() will again fail
on any select/poll errors different than EINTR.

  better control at the exact state of the connection's SSL status so that we

  It was a hack to begin with and since it doesn't work and hasn't worked
  correctly for a long time and nobody has even noticed, I consider it a very
  suitable subject for plain removal. And so it was done.

  get a fresh one downloaded and created with 'make ca-bundle' or you can get
