7e0b0763fc Revert Joshua Kwan's patch committed 11 Sep 2009.
Some systems poll function sets POLLHUP in revents without setting
POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
libcurl code execution paths this could trigger busy wait loops with
high CPU usage until a timeout condition aborted the loop.

The reverted patch addressed the above issue for a very specific case,
when awaiting c-ares to resolve. A libcurl-wide fix superceeds this one.

4002fbe1f5 Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
This fixes a loop problem with high CPU usage.

9770899a4b Moved potential inclusion of system's malloc.h and memory.h header files to
setup_once.h.  Inclusion of each header file is based on the definition of
NEED_MALLOC_H and NEED_MEMORY_H respectively.

dcf92bffd2 - When building with c-ares 1.6.1 (not yet released) or later and IPv6 support
enabled, we can now take advantage of its brand new AF_UNSPEC support in
  ares_gethostbyname(). This makes test case 241 finally run fine for me wtih
  this setup since it now parses the "::1 ip6-localhost" line fine in my
  /etc/hosts file!

0cd8840dba - Andreas Schuldei improved Phil Blundell's patch for IPv6 using c-ares, and I
edited it slightly. Now you should be able to use IPv6 addresses fine even
  with libcurl built to use c-ares.

4c663ba9a8 When transferring 500 downloads in parallel with a c-ares enabled build only
to find that it crashed miserably, and this was due to some select()isms left
in the code. This was due to API restrictions in c-ares 1.3.x, but with the
upcoming c-ares 1.4.0 this is no longer the case so now libcurl runs much
better with c-ares and the multi interface with > 1024 file descriptors in
use.

eed47311f8 New Internal wrapper function Curl_select() around select (2), it
uses poll() when a fine poll() is available, so now libcurl can be
built without select() support at all if a fine poll() is available.

91386937ff - Michael Wallner provided a patch that adds support for CURLOPT_TIMEOUT_MS
and CURLOPT_CONNECTTIMEOUT_MS that, as their names should hint, do the
  timeouts with millisecond resolution instead. The only restriction to that
  is the alarm() (sometimes) used to abort name resolves as that uses full
  seconds. I fixed the FTP response timeout part of the patch.

  Internally we now count and keep the timeouts in milliseconds but it also
  means we multiply set timeouts with 1000. The effect of this is that no
  timeout can be set to more than 2^31 milliseconds (on 32 bit systems), which
  equals 24.86 days.  We probably couldn't before either since the code did
  *1000 on the timeout values on several places already.

e85e30546c Roland Blom filed bug report #1481217
(http://curl.haxx.se/bug/view.cgi?id=1481217), with follow-ups by Michele Bini
and David Byron. libcurl previously wrongly used GetLastError() on windows to
get error details after socket-related function calls, when it really should
use WSAGetLastError() instead.

When changing to this, the former function Curl_ourerrno() is now instead
called Curl_sockerrno() as it is necessary to only use it to get errno from
socket-related functions as otherwise it won't work as intended on Windows.

e36fb1ecda Curl_wait_for_resolv() no longer disconnects on failure, but leaves that
operation to the caller. Disconnecting has the disadvantage that the conn
pointer gets completely invalidated and this is not handled on lots of places
in the code.

c39858aac0 Source cleanups. The major one being that we now _always_ use a Curl_addrinfo
linked list for name resolved data, even on hosts/systems with only IPv4
stacks as this simplifies a lot of code.
