HoneyryderChuck a03e93e531 allow for oportunistic upgrades, such as the apache Upgrade: h2
this is achieved by a rework of the upgrade plugin, and the addition of
an h2 upgrade plugin. The idea is the following: if a response carries
an Upgrade header, and there's a handler for it, we should go for it.
The difference is:

* when the response is 101, this means that the negotiation must take
  place before the actual response comes in;
* when the response is 200, upgrading means reconnecting to the channel,
  and assume the new protocol for subsequent requests only.
