Fixed bug report #2958074 indicating
(http://curl.haxx.se/bug/view.cgi?id=2958074) that curl on Windows with
option --trace-time did not use local time when timestamping trace lines.
This could also happen on other systems depending on time souurce.

- SMTP falls back to RFC821 HELO when EHLO fails (and SSL is not required).
- Use of true local host name (i.e.: via gethostname()) when available, as default argument to SMTP HELO/EHLO.
- Test case 804 for HELO fallback.

  properly in angle brackets. Recipients provided with CURLOPT_MAIL_RCPT now
  get angle bracket wrapping automatically by libcurl unless the recipient
  starts with an angle bracket as then the app is assumed to deal with that
  properly on its own.

  full DATA has been sent, and I modified the test SMTP server to also send
  that response. As usual, the DONE operation that is made after a completed
  transfer is still not doable in a non-blocking way so this waiting for 250
  is unfortunately made blockingly.

removed trailing whitespace

Overhauled test suite getpart() function. Fixing potential out of bounds
stack and memory overwrites triggered with huge test case definitions.

  in the same RCPT TO line, when they should be sent in separate single
  commands. I updated test case 802 to verify this.

- I also fixed a bad use of my_setopt_str() of CURLOPT_MAIL_RCPT in the curl
  tool which made it try to output it as string for the --libcurl feature
  which could lead to crashes.

mention last changes

  to automatically uncompress it with the CURLOPT_ENCODING option, libcurl
  could wrongly provide the callback with more data than what the maximum
  documented amount. An application could thus get tricked into badness if the
  maximum limit was trusted to be enforced by libcurl itself (as it is
  documented).

  This is further detailed and explained in the libcurl security advisory
  20100209 at

    http://curl.haxx.se/docs/adv_20100209.html

Makefile.inc since that can't be included directly.

mention a couple of changes back from November

- Symbol CURL_FORMAT_OFF_T now obsoleted, will be removed in a future release,
  symbol will not be available when building with CURL_NO_OLDIES defined. Use
  of CURL_FORMAT_CURL_OFF_T is preferred since 7.19.0

simply check for CURLM_CALL_MULTI_PERFORM internally. This has the added
benefit that this goes in line with my long-term wishes to get rid of the
CURLM_CALL_MULTI_PERFORM all together from the public API.

mention asynchronous DNS lookups enhancements

  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.

  interval even during very slow connects.

  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.

  available.

was a bit too quick and broke test case 1101 with that change. The order of
some of the setups is sensitive. I now changed it slightly again.
