Dirk Manske made the share-locking around DNS lookups a bit "looser" so that
...
multiple DNS lookups can run simultaneously faster. The downside is that
resolving the same host name now can be made at once from multiple threads,
but the upside is that threads now don't alwys have to wait for the others'
resolves. Test case 506 updated accordingly.

Based on a patch provided by Siddhartha Prakash Jain. In Curl_resolv() when
...
my_getaddrinfo() has been called (and wait has been set to TRUE), we check
if the name already is resolved and if so don't return wait status to the
parent. This can happen with IP-only names.

NOT free the existing hash entry when we try to add a new one that matches
an existing entry. We now instead free the new one, and make the parent

EAGAIN on older (correct) glibc versions indicate a problem and not the need
...
for a bigger buffer and this is indeed badness for us. Making this work
on both old and new glibc versions require an ugly loop that in its worse
form cause 45 bad loops when using the correct glibc and a non-resolving
host name... :-/
We want a better fix. Badly.

Curl_resolv() now returns a different struct, and it contains a reference

counter so that the caller needs to decrease that counter when done with
the returned data.
If compiled with MALLOCDEBUG I've added some extra checking that the counter
is decreased before a handle is closed etc.
