quakespasm: Update to 0.93.1

pkgsrc changes:

Use more recent middleware (SDL2) and mp3 (mpg123) libraries

Changes in 0.93.1:

Fixed a fog regression which was introduced in 0.93.0.
Fixed a crash (buffer overflow) with invalid vis data.
Fixed buttons crushing players in 64-bit builds.
Change controller movement to use cubic easing by default; added \ 
"joy_exponent_move" cvar.
config.cfg is no longer written in case of a Sys_Error.
Fixed Opus encoded cd tracks not being recognized as ripped tracks.
Update the third-party libraries. Other fixes/cleanups.

Changes in 0.93.0:

Raise default "joy_deadzone_trigger" cvar to 0.2.
Raise console buffer size to 1MB.
Raise MAX_STATIC_ENTITIES from 512 to 4096.
Raise MAX_STACK_DEPTH from 32 to 64.
Raise command buffer size from 8K to 256K to support large configs.
Remove MAX_EFRAGS and MAX_MAP_LEAFS limits.
Remove "Loadgame buffer overflow" limit, which could happen when \ 
loading DP or QSS saves.
Adjust "exceeds standard limit of" debug warnings to include the \ 
actual QS limit.
Change "game" command to now exec quake.rc.
Change "games" / "mods" commands to list all subdirectories.
Restore vid_refreshrate from fitzquake-0.85 for SDL2 builds.
Alpha-masked model support. (MF_HOLEY: 0x4000).
Invalid skin index now draws skin 0 (WinQuake behaviour) instead of blue \ 
checkerboard.
Change default screenshot format to png. The 'screenshot' command now supports \ 
optional format (tga, png or jpg) and quality (1-100) arguments.
Revert "always run" changes from 0.85.9 and move the QuakeSpasm \ 
customizations to a new "cl_alwaysrun" cvar: Set to 1 in order to \ 
scale forward/side/up speed by "cl_movespeedkey" (usually 2), and to \ 
make "speedkey" act as "slowkey".
Change the "always run" menu option to offer three choices:
    off (cl_alwaysrun 0, cl_forwardspeed 200, cl_backspeed 200)
    vanilla (cl_alwaysrun 0, cl_forwardspeed 400, cl_backspeed 400)
    quakespasm (cl_alwaysrun 1, cl_forwardspeed 200, cl_backspeed 200)
New "r_scale" cvar. Set to 2, 3, or 4 to render the view at 1/2, 1/3, \ 
or 1/4 resolution.
New "r_viewmodel_quake" cvar. Set to 1 for WinQuake gun position (from \ 
MarkV).
New "find" / "apropos" command, searches for commands/cvar \ 
names for the given substring (from Spike).
New "randmap" command for loading a random map.
New "gl_cshiftpercent_contents", "gl_cshiftpercent_damage", \ 
"gl_cshiftpercent_bonus", "gl_cshiftpercent_powerup" cvars \ 
for tuning the strength of specic view blends.
GL2 renderer: use a GLSL shader for world faces. Fixes reports of \ 
integrated+discrete GPU laptops having inconsistent fog rendering.
Fix macOS startup delay (avoid calling gethostbyname() for ".local" \ 
hostnames).
Fix memory corruption in PF_lightstyle with out of bounds lightstyles.
Fix crash in BoundPoly with polygons extending beyond +/-9999.
Fix QS window to stay on the current monitor when changing video modes (SDL2 only).
Fix possible freeze in SV_TouchLinks regardless of what QC does in the touch \ 
function.
Fix for maps with empty strings for vector keys (e.g. "origin"); don't \ 
read uninitialized memory.
Support for Open Watcom compiler.
Update the third-party libraries.
