Also update the CHANGELOG and copyright years.

This allows any application to upgrade the protocol options without
having to restart the listener. This is most useful to update the
dispatch list of HTTP servers, for example.
The upgrade is done at the acceptor level, meaning only new connections
receive the new protocol options.

This is a big change in the internal cowboy API. This should not
have any impact on existing applications as only the acceptor is
expected to use these API calls.
The function cowboy_listener:wait/3 has been removed. max_connections
checking now occurs directly in cowboy_listener:add_connection/3.
If the pool is full and the acceptor has to wait, then it doesn't
return, waiting for a free space to be available.
To accomodate these changes, it is now cowboy_listener that will
inform the new connection that it is ready by sending {shoot, self()}.
This should be a great improvement to the latency of responses as
there is one less message to wait for before the request process
can do its work.
Overall the performance under heavy load should also be improved as
we greatly reduce the number of messages sent between the acceptor
and the listener process.

a release upgrade on a vm running cowboy where any other appup
includes an {update, Mod, {advanced, Extra}} instruction will hang
forever due to these child specs being wrong.
The gen_servers should be [Mod] and the non gen_server needs to be []
since there is no callback to handle this.

|
Currently only supports limiting the maximum number of
connections by managing connection pools.
|
|
This is probably not perfect yet but it should be better than
nothing. We'll improve things with feedback received from the
many users.

Following discussions on #erlounge.
Also fixes compilation in R14B03 and fixes a few underspecs
dialyzer warnings.

Moved the Transport:listen call to cowboy_acceptors_sup. This make it
depend on a child of cowboy_listener_sup instead of cowboy_sup, which
isn't getting shut down when calling cowboy:stop_listener/1 and thus
didn't close the listening socket.

* Cowboy isn't an OTP application anymore; just a supervisor.
* All processes started by Cowboy are now anonymous.
* All processes related to a listener are now part of its supervision tree.
