with CURLOPT_PROXY can use a http:// prefix and user + password. The user
and password fields are now also URL decoded properly.

Test case 264 added to verify.

It now properly handles code that uses curl_free() (since not all versions of
curl have it), and also fixes a few problems when detecting libcurl on MinGW,
and a linker problem on OSX Panther.

all tools run in the ares dir - now shown like "running ares/[tool]"

complains and claims this is deprecated.

changes in a slower and more controlled manner...

1) findtool does look per tool in PATH and think ./perl is the perl
executable, while is just a local directory (I have . in the PATH)

2) I got several warning for head -1 deprecated in favour of head -n 1

3) ares directory is missing some file (missing is missing :-) ) because
automake and friends is not run.

(Let's hope number 2 doesn't break somewhere "out there", if so we can always
search/replace that back.)

  Make UDP sockets non-blocking. I've confirmed that at least on Linux 2.4 a
  read event can come back from poll() on a valid SOCK_DGRAM socket but
  recv(2) will still block. This patch doesn't ignore EAGAIN in
  read_udp_packets(), though maybe it should. (This patch was edited by Daniel
  Stenberg and a new configure test was added (imported from curl's configure)
  to properly detect what non-blocking socket approach to use.)

  I'm not quite sure how this was happening, but I've been seeing PTR queries
  which seem to return empty responses. At least, they were empty when calling
  ares_expand_name() on the record. Here's a patch which guarantees to
  NUL-terminate the expanded name. The old behavior failed to NUL-terminate if
  len was 0, and this was causing strlen() to run past the end of the buffer
  after calling ares_expand_name() and getting ARES_SUCCESS as the return
  value. If q is not greater than *s then it's equal and *s is always
  allocated with at least one byte.

- inspired by Tupone Alfredo's bug report (and patch) #1212940

address was not possible to use. It is now, but requires it written
RFC2732-style, within brackets - which incidently is how you enter numerical
IPv6 addresses in URLs. Test case 263 added to verify.

binary zeroes within the headers. They confused libcurl to do wrong so the
downloaded headers become incomplete. The fix is now verified with test case
262.
