This was already implemented but only for the `gamedir` command.

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.

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

This creates a new function, CL_NewQuakeParticle, that is used instead of CL_NewParticle when cl_particles_quake is enabled. The function calls CL_NewParticle with a some hardcoded defaults to make the particle texture a disc, or solid square, based on the value of cl_particles_quake.

Fix two memory allocation issues

In fa06dd40f48b20d738b6bd604758c81defd76cfd I misunderstood the
subdivision code, causing sentinel2 to be written past the end of the
buffer... somehow many maps and games worked fine despite this. This
commit reverts the bad line from that commit.

A very old (div0-stable) bug when loading Q1BSP meant we didn't allocate
enough texture memory when a "sky" texture name wasn't all lowercase,
causing a crash when loading custom map e2m9.

server: always use correct case for map names

Previously whatever was typed in as the map/changelevel argument was
used even if it didn't match the case of the filename in the pak, which
meant QC could see multiple instances of the same map that differed only
by case, causing problems for gameplay stats.

Now DP will always use the same case as the real .bsp filename for the
`mapname` globals, and the sv_world* and cl_world* cvars, and the server
status and getinfo/getstatus responses.  This matches the behaviour of
QC code which retrieved the name from the VFS, such as the `gotomap` and
voting code in Nexuiz and Xonotic.

SVVM: Fix segfault during shutdown, improve previous commit

In 30c47b1aff3ac28359c469a40c44ee700c80e814 a bug in SVVM_reset_cmd was
revealed because that code never ran before that commit:
sometimes the server segfaulted at end of match because SVVM_reset_cmd
called QC code even though SVVM_reset_cmd would only be called by
PRVM_Prog_Reset after it had freed the tempstring memory... so if QC
created a tempstring, crash.

This commit refactors the SV VM shutdown to be consistent with the CL
and MENU shutdown by moving the QC SV_Shutdown() call into a separate
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
map (like in previous versions).
