gfe-relnote: Introduce kDefaultUdpPacketControlBufferSize and use it in QuicPacketReader as the control buffer size. No behavior change, not protected.
Why? I need to remove kCmsgSpaceForReadPacket, which is defined in quic_socket_utils.h.
Merge note: Please define kCmsgSpaceForGooglePacketHeaderImpl=0 in Chromium's quic_udp_socket_platform_impl.h.
