Reduce the amount of unnecessary messages shown in the game chat
Some engine messages are being printed to chat in scenarios where they may obscure regular game chat.
To help with this, I've adjusted the visibility of them:
- "unconnected changed name to BOT" and "BOT left the game" showing in chat have been disabled by only allowing such messages to show for real clients
Bots will still show that they've been dropped in the console and Xonotic still shows a (dis)connect message
- Verbose "Server lag report" messages (most commonly seen during map votes) have been moved to the console

edict: fix escape parsing and make exceptions configurable
In 312123ecffc7e3dd892c7df754c911b47b9cdfaa a bug was introduced where
newlines were no longer supported in string fields.
This patch supports them again, which requires exceptions be
reintroduced to fully support some buggy maps, but this time there's a
cvar for documentation and adjustment. The other notes and fixes in
https://github.com/DarkPlacesEngine/darkplaces/pull/185 still apply.
The code introduced in 42e86ab7892c3d8f5373402a714b73b2e040d81b had two
separate modes which was more complex than necessary and less robust in
high ping high jitter scenarios.
The 0ms packet check didn't work when the cause was aggressive time
synchronisation and a ping spike.
In 3d8f1ca7b142c0a9fd8c3b4a494b62dcce39ab71 a horizontal player speed
calculation was changed to include the vertical velocity and to no
longer be the speed, by use of the wrong macro.
This patch reverts those changes and adds a macro for this calculation.

This doesn't fix them, it just changes the behaviour of the map bug so

Fixes MVM getgamedirinfo() builtin returning stale data (wasn't updated

events meant for MENU QC after MR_Shutdown() but before MR_Init() (by
calling directly instead of adding `menu_restart` to the cbuf).

fs: recognise mods by -game cmdline args, deduplicate gamedirs, refactoring
Players often start mods using -game even when they have their own
cmdline option, and modders often provide scripts which use -game.
This was already implemented but only for the `gamedir` command.
Refactoring was required to avoid chicken vs egg problems when doing it
with cmdline gamedirs too.
Fixes a bug: the first gamedir (in the cmdline or `gamedir` args) was
used to identify the mod but it needs to be the last one that matches
because the last gamedir is the primary (first in the search path, and
where files are saved).
Includes supported game and mod directories in the main gamedir list for
interface consistency, less special cases, and to support deduplication.
Refactoring was required in the menu modlist where there was also an
opportunity to simplify.

Implements hardware refresh rate modesetting, this wasn't implemented
yet for SDL2 (although it was partially supported in c03b106680122333189e42294c4fb3c385307631).
Implements colour depth modesetting but leaves it disabled because
almost all display hardware supports 24bpp only.
Properly integrates desktopfullscreen and display selection into the
modesetting design.
Changes the modesetting design to better suit SDL2 (see comments),
using the code for immediately applying cvar changes in the startup path
too.
Disables immediate-apply of display cvar changes when hardware
modesetting is active and the player is accessing a menu, because
traditional menu designs don't support it: they make players scroll
through a list of resolutions, setting the cvars at each step.
Enables modesetting on Linux: turns out it does still work in SDL2 even
though exclusive fullscreen support was removed. SDL2 replaced
exclusive fullscreen with desktopfullscreen combined with an xrandr
modeset (behaves like desktopfullscreen IF the mode is the same
as the desktop one).
Replaces the 640x480 modesetting fallback with desktopfullscreen, should
be nicer and should always work (the old fallback is still there but
should never be reached).
Adds a debug print of all modes supported by the display (at startup).
Updates modesetting console prints.
Works around an SDL bug when increasing hardware resolution.
Works around an SDL bug where it doesn't set the error string in
SDL_GetClosestDisplayMode() so SDL_GetError would return some unrelated
message.
This uses a viddef_mode_t `vid.mode` in the global viddef_t `vid`
instead of having a separate declaration of each var there, makes
copying it more efficient.
Moves setting of cvars from VID_Mode into VID_Restart_f because we only
need to do it if a vid_restart fails after changes were made, during
normal startup the only source of config changes is the fallbacks cvar
array which already sets them as they're tested.
This avoids unnecessary clobbering and callbacks under normal
circumstances and makes vid_restart code more self-contained.
Refers to cvars by pointer instead of string for robustness.
Removes persistent storage of last known good mode, it's only needed in
VID_Restart_f and it would be verbose and error-prone to keep it updated
as well as the current mode when applying cvar changes and SDL events.

high DPI Windows test machine.
Uses CLOCK_MONOTONIC_RAW on Linux, this is unaffected by synchronisation
adjustments and is used by SDL_GetPerformanceCounter() (we'll use it
directly to support dedicated servers without SDL).
Removes gettimeofday() and usleep() which were marked obsolete and
removed in POSIX.1-2008 so the old comment // FIXME improve this check
was impossible to address. The gettimeofday() replacement is very well
tested now (sys_useclockgettime 1 is default even in div0-stable).
