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.
to return a linked lists of results. These were also modified to internally
use the ares_data memory struct and as such its result must be free'ed with
ares_free_data().
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.

its pkg-config file. So -Wl stuff ended up in the .pc file, which is really
bad, and breaks if there are multiple -Wl in our LDFLAGS (which are in
PTXdist). bug #2893592 (http://curl.haxx.se/bug/view.cgi?id=2893592)
implement the function even when h_errno is not a macro.
The h_errno macro test now only done on systems for which there
is no hard coded knowledge about getaddrinfo's thread safeness.
--with-nss is set but not "yes".
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.
the client certificate. It also disable the key name test as some engines
can select a private key/cert automatically (When there is only one key
and/or certificate on the hardware device used by the engine)
- Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
and newer have a threadsafe getaddrinfo.
- Fix Dragonfly BSD triplet detection.
- In case the hard-coded knowledge says that getaddrinfo is threadsafe,
an additional check is done to verify that h_errno is also defined.
If h_errno isn't defined, we finally assume that it isn't threadsafe.
Jamie Lokier provided the inspiration for this extra check.
No need for a separate variable ndns.
The memory leak detection will detect code that fails to release a dns reference.
The DEBUGASSERT will detect code that releases too many references.

before and always closed unresolved. More info at the RH bug:

(http://curl.haxx.se/bug/view.cgi?id=2891595) which identified how an entry
in the DNS cache would linger too long if the request that added it was in
use that long. He also provided the patch that now makes libcurl capable of
still doing a request while the DNS hash entry may get timed out.
used during the FTP connection phase (after the actual TCP connect), while
it of course should be. I also made the speed check get called correctly so
that really slow servers will trigger that properly too.
