Cloned from CL 231494986 by 'g4 patch'.
Original change by bnc@bnc:majom-bnc-chromium-google3-headers-git5:2181:citc on 2019/01/29 16:21:02.
Send HEADERS on the request stream.
In QUIC version 99, send HEADERS (including trailers) on the request stream
instead of the headers stream, compressed with QPACK instead of HPACK.
gfe-relnote: Send HEADERS on the request stream in QUIC version 99 only. Not flag protected.
