[result of work by Markus Goetz as part of QTBUG-9894]

To get HTTP pipelining to work at all on Qt-Symbian, and work better in other Qt ports, the values in initializeMaximumHTTPConnectionCountPerHost() in the following file need to fixed up. 


I verified on N97 that changing the Symbian max value to 3 * (1+3) makes at least a few requests start getting pipelined, where there were previously _zero_ in vanilla Qt 4.6.2.
