proxy that cannot be resolved when using c-ares. This matches the behaviour
  when not using c-ares.

libcurl options for controlling what to get and how to receive posssibly
interleaved RTP data. Initial commit.

  HTTP Cookie: header _needs_ to be sorted on the path length in the cases
  where two cookies using the same name are set more than once using
  (overlapping) paths. Realizing this, identically named cookies must be
  sorted correctly. But detecting only identically named cookies and take care
  of them individually is harder than just to blindly and unconditionally sort
  all cookies based on their path lengths. All major browsers also already do
  this, so this makes our behavior one step closer to them in the cookie area.

  Test case 8 was the only one that broke due to this change and I updated it
  accordingly.

  again when downloading files over FTP using ASCII and it turns out that the
  final size of the file is not the same as the initial size the server
  reported. This is very common since servers don't take the newline
  conversions into account.

  being properly detected under certain circumstances. It had been caused by
  strange behavior of pkg-config when handling PKG_CONFIG_LIBDIR. pkg-config
  distinguishes among empty and non-existent environment variable in that case.

  transfers: curl_multi_fdset() would return -1 and not set and file
  descriptors several times during a transfer of a single file. It turned out
  to be due to two different flaws now fixed. Gil's excellent recipe helped me
  nail this.

  present in the tests/data/Makefile.am and outputs a notice message on the
  screen if not. Each test file has to be included in that Makefile.am to get
  included in release archives and forgetting to add files there is a common
  mistake. This is an attempt to make it harder to forget.

  ossl_connect_step3() increments an SSL session handle reference counter on
  each call. When sessions are re-used this reference counter may be
  incremented many times, but it will be decremented only once when done (by
  Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
  if this reference count remains positive. When a session is re-used the
  reference counter should be corrected by explicitly calling
  SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
  introducing a memory leak.

  name resolves when c-ares is used for resolving.

  versions --ftp-ssl and --ftp-ssl-reqd as these options are now used to
  control SSL/TLS for IMAP, POP3 and SMTP as well in addition to FTP. The old
  option names are still working but the new ones are the prefered ones
  (listed and documented).

  command is a special "hack" used by the drftpd server, but even though it is
  a custom extension I've deemed it fine to add to libcurl since this server
  seems to survive and people keep using it and want libcurl to support
  it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also
  usable from the curl tool with --ftp-pret. Using this option on a server
  that doesn't support this command will make libcurl fail.

  headers work correctly even on FreeBSD systems before v8.

some of the setups is sensitive. I now changed it slightly again.

  detects and uses proxies based on the environment variables. If the proxy
  was given as an explicit option it worked, but due to the setup order
  mistake proxies would not be used fine for a few protocols when picked up
  from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added
  test case 1106 that verifies this functionality.

  on FTP errors in the transient 5xx range. Transient FTP errors are in the
  4xx range. The code itself only tried on 5xx errors that occured _at login_.
  Now the retry code retries on all FTP transfer failures that ended with a
  4xx response.

  curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
  data->state.expect100header accordingly - the current code (in 7.19.7 at
  least) doesn't handle this properly. Martin Storsjo provided the fix!

- Added Diffie-Hellman parameters to several test harness certificate files in
  PEM format. Required by several stunnel versions used by our test harness.

  rework patch that now integrates TFTP properly into libcurl so that it can
  be used non-blocking with the multi interface and more. BLKSIZE also works.

  The --tftp-blksize option was added to allow setting the TFTP BLKSIZE from
  the command line.

  though it failed to write a very small download to disk (done in a single

  there was insufficient error-checking for the fclose() call which tricked
  curl to believe things were fine.

  CURLOPT_HTTPPROXYTUNNEL enabled over a proxy, a subsequent request using the

Added '--configure' option to curl-config to display original configure arguments when curl was built

  I think we can still improve that to check for pkg-config in that path etc,
  but at least this patch brings back the same functionality we had before.
