In QUIC, we have an architectural need (in future, when we implement 0-RTT, etc.) to be able to create streams before we start connecting. This requires we allocate a stream, including a stream ID, after creating a QCSO but prior to connecting. However stream IDs are dependent on whether the endpoint is in the client or server role, therefore we must know whether we are going to be a client or server before any pre-connection streams are created. Moreover, the originally defined QUIC_client_method() and QUIC_server_method() functions heavily implied the original plan was to have different SSL_METHODs for clients and servers. Up until now we had been relying on SSL_set_connect/accept_state() instead. Solve these problems by basing client/server identity on whether QUIC_server_method() is used (in future, when we support servers). This ensures that once a QCSO is created its client/server identity are fixed and cannot change, allowing pre-connection stream IDs, etc. to be allocated. Client/server uncertainty was the primary reason why QUIC_CHANNEL creation was deferred until connection time up until now, so this enables further refactoring to facilitate eager allocation of the QUIC_CHANNEL at QCSO allocation time. This is important as allocating a stream including its write buffers is hard without having the QUIC_CHANNEL (which owns the QUIC_STREAM_MAP) in existence.
