VMS build system enhancements by Steven M. Schweda and Craig A. Berry

- Renato Botelho and Peter Pentchev brought a patch that makes the libcurl
headers work correctly even on FreeBSD systems before v8.

fixed a precaution check in the cookie code, pointed out by Julien Chaffraix

- David Byron fixed Curl_ossl_cleanup to actually call ENGINE_cleanup when
available.

- Jon Nelson found a regression that turned out to be a flaw in how libcurl
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.

- Siegfried Gyuricsko found out that the curl manual said --retry would retry
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.

- Constantine Sapuntzakis figured out a case which would lead to libcurl
accessing alredy freed memory and thus crash when using HTTPS (with
OpenSSL), multi interface and the CURLOPT_DEBUGFUNCTION and a certain order
of cleaning things up. I fixed it.

- Martin Storsjo made libcurl use the Expect: 100-continue header for posts
with unknown size. Previously it was only used for posts with a known size
larger than 1024 bytes.

- If the Expect: 100-continue header has been set by the application through
curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
data->state.expect100header accordingly - the

- If the Expect: 100-continue header has been set by the application through
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!

- Markus Koetter provided a polished and updated version of Chad Monroe's TFTP
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.

- Bjorn Augustsson reported a bug which made curl not report any problems even
though it failed to write a very small download to disk (done in a single
fwrite call). It turned out to be because fwrite() returned success, but
there was insufficient error-checking for the fclose() call which tricked
curl to believe things were fine.

- Jad Chamcham pointed out a bug with connection re-use. If a connection had
CURLOPT_HTTPPROXYTUNNEL enabled over a proxy, a subsequent request using the
same proxy with the tunnel option disabled would still wrongly re-use that
previous connection and the outcome would only be badness.

end up with entries that wouldn't time-out:

1. Set up a first web server that redirects (307) to a http://server:port
that's down
2. Have curl connect to the first web server using curl multi

After the curl_easy_cleanup call, there will be curl dns entries hanging
around with in_use != 0.

- Claes Jakobsson restored the configure functionality to detect NSS when

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.
