QHttpNetworkConnection: fall back gracefully to HTTP/1.1
Both SPDY and HTTP/2 work with a single qhttpnetworkchannel (and this means one
socket per qhttpnetworkconnection). Normally, HTTP/1.1 connection is using up to 6
channels/sockets though. At the moment a failure to negotiate SPDY/HTTP/2 leaves us
with a downgraded HTTP/1.1 connection (with only one channel vs. default 6).
Since we initialize channels (and establish connections) in a 'lazy' manner
it's ok to pre-allocate all 6 channels and then either use 1 (if SPDY/HTTP/2
indeed was negotiated) or switch back to 6 in case of failure.
