This commit includes a (highly) modified version of Chocolate DOOM which can run on NuttX. The majority of the modifications were made to pass the NuttX style check. Some small modifications have been added to support keyboard input, render graphics to frame buffers and directly use the POSIX interfaces NuttX supplies, stripping out Windows/Mac stuff and any references to SDL. NOTE: Sound is currently not supported in any capacity, nor is the networking stuff. A lot of Chocolate DOOM code was stripped out since it was unused. If there is a need/desire to add it back later, the original Chocolate DOOM source can be used as a reference. WARNING: The NuttX keyboard codec is incredibly non-standard and so there are problems translating from X11 keys to NuttX ones to play DOOM. Right now, the CTRL key for firing doesn't work because the NuttX codec has no concept of it. The NuttX codec should be modified (and other input devices supported), but at the time of this port I am not sufficiently comfortable doing so since I am afraid of breaking other things in the kernel. NOTE: This port (and likely the original DOOM) seems to be written with 32-bit computers in mind. As such, most things are given the type of natural `int`, even when a single byte might do. There are significant size optimizations that could be made to make this more suited to embedded devices that NuttX typically runs on. Signed-off-by: Matteo Golin <matteo.golin@gmail.com>
