- Introduced a SYST-based test to properly set-up name format when dealing  with the OS/400 FTP server.
- Fixed an ftp_readresp() bug preventing detection of failing control socket  and causing FTP client to loop forever.

  read stdin in a non-blocking fashion. This also brings back -T- (minus) to
  the previous blocking behavior since it could break stuff for people at
  times.

  strdup() that could lead to segfault if it returned NULL. I extended his
  suggest patch to now have Curl_retry_request() return a regular return code
  and better check that.

  sending of the TSIZE option. I don't like fixing bugs just hours before
  a release, but since it was broken and the patch fixes this for him I decided
  to get it in anyway.

  each test, so that the test suite can now be used to actually test the
  verification of cert names etc. This made an error show up in the OpenSSL-
  specific code where it would attempt to match the CN field even if a
  subjectAltName exists that doesn't match. This is now fixed and verified
  in test 311.

  warnings when mixing ints and bools.

torture tests to fail.

  should introduce an option to disable SNI, but as we're in feature freeze
  now I've addressed the obvious bug here (pointed out by Peter Sylvester): we
  shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected.
  Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular
  option for SNI, or are we simply not using it?

  (http://curl.haxx.se/bug/view.cgi?id=2829955) mentioning the recent SSL cert
  verification flaw found and exploited by Moxie Marlinspike. The presentation
  he did at Black Hat is available here:
  https://www.blackhat.com/html/bh-usa-09/bh-usa-09-archives.html#Marlinspike

  Apparently at least one CA allowed a subjectAltName or CN that contain a
  zero byte, and thus clients that assumed they would never have zero bytes
  were exploited to OK a certificate that didn't actually match the site. Like
  if the name in the cert was "example.com\0theatualsite.com", libcurl would
  happily verify that cert for example.com.

  libcurl now better use the length of the extracted name, not assuming it is
  zero terminated.

  only in some OpenSSL installs - like on Windows) isn't thread-safe and we
  agreed that moving it to the global_init() function is a decent way to deal
  with this situation.

  CURLOPT_NOPROXY to "*", or to a host that should not use a proxy, I actually
  could still end up using a proxy if a proxy environment variable was set.

  CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
  send when using FTP, as a sign that libcurl shall simply ignore the response
  from the server instead of treating it as an error. Not treating a 400+ FTP
  response code as an error means that failed commands will not abort the
  chain of commands, nor will they cause the connection to get disconnected.

  out that OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm,
  and provided the solution too: to use OpenSSL_add_all_algorithms() instead
  of the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in
  OpenSSL 0.9.5

  They introduce known_host support for SSH keys to libcurl. See docs for
  details.

  (https://bugzilla.novell.com/523919). When looking at the code, I found
  that also the ptr pointer can leak.

  in NSS-powered libcurl. Now the client certificates can be selected
  automatically by a NSS built-in hook. Additionally pre-login to all PKCS11
  slots is no more performed. It used to cause problems with HW tokens.

- Fixed reference counting for NSS client certificates. Now the PEM reader
  module should be always properly unloaded on Curl_nss_cleanup(). If the unload
  fails though, libcurl will try to reuse the already loaded instance.

in the Watcom makefiles aren't quite correct).

  errno is not reset on success.

renamed generated config.h to curl_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.

  setting a file descriptor non-blocking. Used by the functionality Eric
  himself brough on June 15th.

  (http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
  problem:

  Url A is accessed using auth. Url A redirects to Url B (on a different
  server0. Url B reuses a persistent connection. Url B has auth, even though
  it's on a different server.

  Note: if Url B does not reuse a persistent connection, auth is not sent.

Markus Koetter provided a patch to avoid getnameinfo() usage which broke a couple of both IPv4 and IPv6 autobuilds.

  range if given colon-separated after the host name/address part. Like
  "192.168.0.1:2000-10000"

  (no newline translations). Use -B/--use-ascii if you rather get the ascii
  approach.

  provided in the url, add it there (squid needs this).

  This allows curl(1) to be used as a client-side tunnel for arbitrary stream
  protocols by abusing chunked transfer encoding in both the HTTP request and
  HTTP response.  This requires server support for sending a response while a
  request is still being read, of course.

  If attempting to read from stdin returns EAGAIN, then we pause our sender.
  This leaves curl to attempt to read from the socket while reading from stdin
  (and thus sending) is paused.

changed testcurl script to allow building test harness
programs when cross-compiling for a *-*-mingw* host.
