HTTP/3: reordered H3_MISSING_SETTINGS and H3_FRAME_UNEXPECTED.
The quic-http-34 is ambiguous as to what error should be generated for the
first frame in control stream:
Each side MUST initiate a single control stream at the beginning of
the connection and send its SETTINGS frame as the first frame on this
stream. If the first frame of the control stream is any other frame
type, this MUST be treated as a connection error of type
H3_MISSING_SETTINGS.
If a DATA frame is received on a control stream, the recipient MUST
respond with a connection error of type H3_FRAME_UNEXPECTED.
If a HEADERS frame is received on a control stream, the recipient MUST
respond with a connection error of type H3_FRAME_UNEXPECTED.
Previously, H3_FRAME_UNEXPECTED had priority, but now H3_MISSING_SETTINGS has.
The arguments in the spec sound more compelling for H3_MISSING_SETTINGS.
