fee68fc612 quake: synchronize Mod_LoadModel and S_LoadSound
This is not a very pretty fix, but code that doesn't crash is better than
code that crashes... "If it runs, it's done."

94109a9506 quake: fix file loading errors
Forgot a return statement in Sys_FileRead (which slipped by since I've made
the questionable decision to disable all warnings...)

5e0bd5bfc0 quake: add notification upon strange error
For some reason a NULL pointer creeps in, on the simulator only, it seems.
This makes sure that if it happens on target we'll know about it.

caee6c578d quake: fix race condition
COM_LoadStackFile was not thread-safe since it relied on a global variable
to pass the loadbuf parameter to COM_LoadFile. This was causing mysterious
crashes when model loading and audio mixing were happening simultaneously.

feacbcd639 quake: cache files in memory to eliminate skips
This caches large files (arbitrarily defined as >1MB) in memory, which
reduces the delay when a new model or sound is needed.

7e4902bf6b quake: fix errorneous endian-correcting reads
ef9ee89 introduced Read{Big,Little}{Short,Long,Float} functions to safely
read a value in memory. These incorrectly take char*, which causes them to
output erroneous 0xff bytes when given bytes with bit 7 set.

2ca47176f9 quake: pack structs which could potentially be unaligned
The d*_t structs are from "d"isk, which means they could be
unaligned. Packing them saves me from having to rewrite every single
access to them.

5d05b9d3e9 Quake!
This ports id Software's Quake to run on the SDL plugin runtime. The
source code originated from id under the GPLv2 license. I used
https://github.com/ahefner/sdlquake as the base of my port.

Performance is, unsurprisingly, not on par with what you're probably
used to on PC. I average about 10FPS on ipod6g, but it's still
playable.

Sound works well enough, but in-game music is not supported. I've
written ARM assembly routines for the inner sound loop. Make sure you
turn the "brightness" all the way down, or colors will look funky.

To run, extract Quake's data files to /.rockbox/quake. Have fun!

152e415b0d wolf3d: fix FM OPL alignment bug in a cleaner way
wl_def.h has a #pragma pack(1), which causes issues when we take the
address of an unaligned struct field. This fixes the issue by
disabling packing in fmopl_gpl.c.

3f59fc8b77 Wolfenstein 3-D!
This is a port of Wolf4SDL, which is derived from the original id
software source release. The port runs on top of the SDL plugin
runtime and is loaded as an overlay.

Licensing of the game code is not an issue, as discussed below
(essentially, the Debian project treats Wolf4SDL as GPLv2, with an
email from John Carmack backing it up):

  http://forums.rockbox.org/index.php?topic=52872

Included is a copy of MAME's Yamaha OPL sound chip emulator
(fmopl_gpl.c).  This file was not part of the original Wolf4SDL source
(which includes a non-GPL'd version), but was rather rebased from from
a later MAME source which had been relicensed to GPLv2.

cf07bb328d duke3d: further optimize audio mixing
Rather than holding intermediate results as fixed-point, this converts them
directly to normal integers (in the range of the PCM sample) while mixing,
instead of waiting till the end to perform a separate shifting step. Also,
this precalculates some constants in the reverb code.
