HTTP/3: proper uni stream closure detection.
Previously, closure detection for server-initiated uni streams was not properly
implemented. Instead, HTTP/3 code relied on QUIC code posting the read event
and setting rev->error when it needed to close the stream. Then, regular
uni stream read handler called c->recv() and received error, which closed the
stream. This was an ad-hoc solution. If, for whatever reason, the read
handler was called earlier, c->recv() would return 0, which would also close
the stream.
Now server-initiated uni streams have a separate read event handler for
tracking stream closure. The handler calls c->recv(), which normally returns
0, but may return error in case of closure.
