MINOR: h2: create the h2s struct and the associated pool
This describes an HTTP/2 stream with its relation to the connection
and to the conn_stream on the other side.
For now we also allocate request and response state for HTTP/1 because
the internal HTTP representation is HTTP/1 at the moment. Later this
should evolve towards a version-agnostic representation and this H1
message state will disappear.
It's important to consider that the streams are necessarily polarized
depending on h2c : if the connection is incoming, streams initiated by
the connection receive requests and send responses. Otherwise it's the
other way around. Such information is known during the connection
instanciation by h2c_frt_init() and will normally be reflected in the
stream ID (odd=demux from client, even=demux from server). The initial
H2_CS_PREFACE state will also depend on the direction. The current h2c
state machine doesn't allow for outgoing connections as it uses a single
state for both (rx state only). It should be the demux state only.
