Conflicts:
- rasterizer.h: upstream raised the transparent geometry groups to 2048
as we had (halo_port_capacity.h); theirs.
- d3d8_gl.c: the ES capabilities' log with upstream's base vertex and our
multiview.
- p2p.c, p2p_internal.h, p2p_signal.c: upstream's several joins and
reconnect, with our join codes' state and the codes' and public list's
updates each pass.
- network_server_manager.c: a machine downloading the map is not refused,
and the bots' room logic stays.
