Add `CURLOPT_COOKIELIST` support

[uvlad7]

Add interface to call curl_easy_setopt - Easy::setopt - with CURLOPT_COOKIELIST.

It's not something like #cookielist=, because I believe this method should be more Rubyish, like add constants for special values, support array argument, or even use CURB_OBJECT_HSETTER instead of simply passing it to libcurl and keep it consistent with other options (like you do this with headers=/CURLOPT_HTTPHEADER, for example, and set enable_cookies flag accordingly). All of this requires much more effort, and I'm happy with this simple raw interface.

Thanks for adding this and agreed with approach would probably like more things to just be handled through the simpler set/get approach. Do you think it would be possible to add to this a test case?

add to this a test case

Sure, gonna take some time, though. Are you OK wit httpbin usage in the test?

[taf2]

httpbin looks interesting, but we have TestServlet already in the test_helper I assume for testing if cookies are set you could add a new endpoint:

  def do_GET(req,res)
    if req.path.match(/redirect$/)
      res.status = 302
      res['Location'] = '/foo'
    elsif req.path.match(/not_here$/)
      res.status = 404
    elsif req.path.match(/error$/)
      res.status = 500
    end
    respond_with("GET#{req.query_string}",req,res)
  end

Maybe something like:

elsif req.path.match(/test_cookies/)

Added tests. Looks like tests/bug_issue277.rb file is missing and was removed after rake package.

Can you please release a new version after this is merged?

[taf2]

Thanks this is great !
