The problem mentioned on Dec 10 2009
(http://curl.haxx.se/bug/view.cgi?id=2905220) was only partially fixed.
Partially because an easy handle can be associated with many connections in
the cache (e.g. if there is a redirect during the lifetime of the easy
handle). The previous patch only cleaned up the first one. The new fix now
removes the easy handle from all connections, not just the first one.
makes sure that when using sub-second timeouts, there's no final bad 1000ms
wait. Previously, a sub-second timeout would often make the elapsed time end
up the time rounded up to the nearest second (e.g. 1s for 200ms timeout)
the global timeout if set. Also, as was reported in the bug report #2956437
by Ryan Chan, the time stamp to use as basis for the per command timeout was
not set properly in the DONE phase for FTP (and not for SMTP) so I fixed
that just now. This was a regression compared to 7.19.7 due to the
conversion of FTP code over to the generic pingpong concepts.

- 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.
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.
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).
