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.
