Update quakespasm to 0.90.0.

Changes in 0.90.0

Fix issues on Windows systems with DPI scaling.
Unix/Mac user directories support. Disabled by default, 'make DO_USERDIRS=1' to \ 
enable it.
SDL2 support. Disabled by default, 'make USE_SDL2=1' to enable it.
Revised keyboard input code.
Revised/improved the 'game' command, i.e. on-the-fly mod changing. It now \ 
accepts an optional second argument for mission packs or quoth support i.e. \ 
-hipnotic, -rogue, or -quoth. For example, for WarpSpasm: "game warp \ 
-quoth"
Command line: "-game {quoth/hipnotic/rogue}" is now treated the same \ 
as -quoth, -hipnotic, or -rogue.
Console speed now resolution-independent.
Disabled gl_zfix, which caused glitches and is undesirable for new maps. \ 
Replacement .ent files to fix z-fighting for several id1 maps added to \ 
quakespasm.pak.
PF_VarString buffer bumped to 1024, avoids truncated centerprints from the 'In \ 
The Shadows' mod.
Support for opengl non-power-of-two-textures extension (disable with command \ 
line: "-notexturenpot".)
Support for OpenGL vertex buffer objects (VBO, OpenGL 1.5 or newer) for world \ 
and brush models (disable with command line: "-novbo".)
Antialiasing (FSAA) support (command line: -fsaa x, where x can be 0, 2, 4, 8).
Fence textures support.
Dynamic light speedup. Speedup loading of tga and pcx external images.
Brush model drawing speedup.
Support for BSP2 and 2PSB map formats.
Support for Opus, FLAC, and tracker music (S3M, IT, UMX, etc.), as compile-time \ 
options.
Music and sfx now mixed at 44100Hz to avoid downsampling music. Low-pass filter \ 
applied to the sfx if -sndspeed is 11025 (the default), to preserve the same \ 
sound quality as 0.85.9. New -mixspeed option sets the rate for mixing sfx and \ 
music, and output to the OS (default 44100), setting it to 11025 reverts to \ 
0.85.9 behaviour. New snd_filterquality cvar, value can be between 1 (emulate OS \ 
X resampler) and 5 (emulate Windows resampler), controls the sound of the \ 
low-pass filter.
Better Hor+ field of view (FOV) scaling behavior.
Better cross-map demo playback support.
Fix screenshots when screen width isn't a multiple of 4.
Fix a lighting glitch due to floating point precision.
Fix a looping sounds glitch.
Fix a vulnerability in file extension handling. Tighten path handling safety.
Initialize opengl with 24-bit depth buffer at 32 bpp.
Reset all models upon gamedir changes. (Fixes failures with mods using custom \ 
content.)
Fix broken behavior upon gamedir changes if -basedir is specified on the command \ 
line.
NET_MAXMESSAGE and MAX_MSGLEN limits bumped to 64000.
MAX_EFRAGS bumped to 4096, and MAX_CHANNELS to 1024.
MAX_ENT_LEAFS bumped from 16 to 32 to work around disappearing or flickering \ 
brush models in some situations. Also, if an entity is visible from \ 
MAX_ENT_LEAFS or more leafs, we now always send it to the client.
Fix cvar cycle command not working sometimes.
Host_Error upon missing models. (Prevents segmentation faults.)
Change sv_aim default value to 1 (i.e. turn off autoaim)
Add 'prev' and 'next' keywords to the 'cd' command.
Work around a linux cdrom issue (playback might not start for a while after a stop).
Quakespasm content customization moved from engine-embedded into a new optional \ 
quakespasm.pak file.
Version bumped to 0.90.0 (because Quakespasm has a decent life of its own)
Other fixes and clean-ups.

Changes in 0.85.9

Fixes for several undefined behaviors in C code (gcc-4.8 support.)
Implemented Hor+ style field of view (FOV) scaling, useful for widescreen \ 
resolutions. Configured by new cvar fov_adapt: set it to 1 and your fov will be \ 
scaled automatically according to the resolution. Enabled by default.
Adjusted string buffers for PR_ValueString and friends to fix crashes with \ 
excessively long global strings seen in some rude mods.
Toned down warning messages from PF_VarString() a bit.
Fixed Fitzquake's map existence check in changelevel (used to leak file handles \ 
which would end up in a Sys_Error() due to consuming all free handles if many \ 
maps reside not in pak files.)
Fixes/cleanups in chat mode handling. Client no longer gets stuck in chat mode \ 
upon disconnect.
Mouse grab/key_dest fixes and key cleanups.
The "speedkey" now acts as "slowkey" when "always \ 
run" is on.
Support for demo recording after connection to server. (thanks to Baker for a patch)

/*..*/ comments.
Changed lightmaps to GL_RGBA instead of GL_RGB.
Better parse for opengl extensions list (from quakeforge.)
Vsync saving/loading fixes.
Fixed pointfile loading.
Multiple cleanups in gl_vidsdl.c.

cross-compiling on Linux.
