Patch against trunk

We noticed two bugs when using the AjpSampler in combination with CookieManager:

A) The cookie header is formatted incorrect and therefore not accepted by the application

B) The cookie information is not passed along to the HTTPSampleResult

Problem A) comes from formatting the cookie via getStringValue(), which returns something like a tab formatted list of the Cookie attributes. You can use a simple JSP or Servlet containing

String cookie=request.getHeader("Cookie");
if (cookie != null) {
    out.println("Cookie: " + cookie);
}

to verify this. The fix consists in using an actual Cookie object instead of a generic JMeterProperty and then retrieving Cookie name and value via getName() and getValue().

Problem B) is fixed by calling res.setCookies().

See the atahced patches.

Thanks for the great Apache JMeter software!
