QUIC: stream limits in "hq" mode. The "hq" mode is HTTP/0.9-1.1 over QUIC. The following limits are introduced: - uni streams are not allowed - keepalive_requests is enforced - keepalive_time is enforced In case of error, QUIC connection is finalized with 0x101 code. This code corresponds to HTTP/3 General Protocol Error.
