"HttpOnly" feature introduced by Microsoft and apparently also supported by
  Firefox: http://msdn2.microsoft.com/en-us/library/ms533046.aspx . HttpOnly
  is now supported when received from servers in HTTP headers, when written to
  cookie jars and when read from existing cookie jars.

  the SingleRequest one to make pipelining better. It is a bit tricky to keep
  them in the right place, to keep things related to the actual request or to
  the actual connection in the right place.

51.Kevin Reed's reported problem with a proxy when doing CONNECT and it
  wants NTLM and close the connection to the initial CONNECT response:
  http://curl.haxx.se/bug/view.cgi?id=1879375

added curl.res to clean target.

  crash!

  working on other IP-addresses or port numbers.

release but hopefully they'll all be fixed in 7.18.1...

pipelining. Broken connection is not restored and we get into infinite
loop. It happens because of wrong is_in_pipeline values.

  (http://curl.haxx.se/bug/view.cgi?id=1879375) which describes how libcurl
  got lost in this scenario: proxy tunnel (or HTTPS over proxy), ask to do any
  proxy authentication and the proxy replies with an auth (like NTLM) and then
  closes the connection after that initial informational response.

  libcurl would not properly re-initialize the connection to the proxy and
  continue the auth negotiation like supposed. It does now however, as it will
  now detect if one or more authentication methods were available and asked
  for, and will thus retry the connection and continue from there.

- I made the progress callback get called properly during proxy CONNECT.

did "SESS". Fixed now.

removed inclusion of libcurl memory debug headers since this lib stub is a well proofed method suggested by Novell. This enables usage of the stub with language bindings.

it when sys/poll.h is unavailable

that it is bad anyway. Starting now, removing a handle that is in used in a
pipeline will break the pipeline - it'll be set back up again but still...
