reworked network addresses to separate address family and connection type. this should make banning people more reliable, as well as simplifying a whole load of logic (no need to check for ipv4 AND ipv6).
tcpconnect will keep trying to connect even if the connection wasn't instant, instead of giving up instantly.
rewrote tcp connections quite a bit. sv_port_tcp now handles qtv+qizmo+http+ws+rtcbroker+tls equivalents.
qtv_streamport is now a legacy cvar and now acts equivalently to sv_port_tcp (but still separate).
rewrote screenshot and video capture code to use strides. this solves image-is-upside down issues with vulkan.
ignore alt key in browser port. oh no! no more red text! oh no! no more alt-being-wrongly-down-and-being-unable-to-type-anything-without-forcing-alt-released!
reworked audio decoder interface. now has clearly defined success/unavailable/end-of-file results. this should solve a whole load of issues with audio streaming.
fixed various openal audio streaming issues too. openal also got some workarounds for emscripten's poor emulation.
fixed ogg decoder to retain sync properly if seeked.
updated menu_media a bit. now reads vorbis comments/id3v1 tags to get proper track names. also saves the playlist so you don't have to manually repopulate the list so it might actually be usable now (after how many years?)
r_stains now defaults to 0, and is no longer enabled by presets. use decals if you want that sort of thing.
added fs_noreexec cvar, so configs will not be reexeced on gamedir change. this also means defaults won't be reapplied, etc.
added 'nvvk' renderer on windows, using nvidia's vulkan-inside-opengl gl extension. mostly just to see how much slower it is.
fixed up the ftp server quite a lot. more complete, more compliant, and should do ipv6 properly to-boot. file transfers also threaded.
fixed potential crash inside runclientphys.
experimental sv_antilag=3 setting. totally untested. the aim is to avoid missing due to lagged knockbacks. may be expensive for the server.
browser port's websockets support fixed. experimental support for webrtc ('works for me', requires a broker server).
updated avplug(renamed to ffmpeg so people know what it is) to use ffmpeg 3.2.4 properly, with its new encoder api. should be much more robust... also added experimental audio decoder for game music etc (currently doesn't resample, so playback rates are screwed, disabled by cvar).
