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).

Make the Sys_Error() message more informative
Re: 24550510e6ff331c1749707df7fad608f618bdd3 as discussed in chat, there
was a good reason to change this word: it indicates DP deliberately
stopped execution, whereas "Error" is generic (most problems that can
happen on a computer are some form of error). Also "Engine Error"
makes it sound like there's a bug in DP, which isn't necessarily the
case: there are several scenarios where user error can trigger this.
This message was already different from Quake's "Quake Error".
Pragmatically speaking, absent any good reason otherwise, naming conventions for functions like Sys_Error should remain consistent with Quake for developer sanity.

sometimes the server segfaulted at end of match because SVVM_reset_cmd

created a tempstring, crash.
This commit refactors the SV VM shutdown to be consistent with the CL

func that (optionally) resets the VM afterwards. As per 30c47b1aff3ac28359c469a40c44ee700c80e814 we MUST reset when stopping a
server to avoid crashes later, but we can still skip it when changing
