syzlang: recognizable file extensions

[xairy]

Currently, syzkaller uses the .txt file extension for syzlang descriptions and uses no file extension for syzlang programs. It would be great to define, document, and use recognizable file extensions for both. This can be useful for e.g. text editors to recognize file format and enable proper syntax highlighting.

Options that come to mind:

• .syz for descriptions and .prog for programs;
• .syzlang for descriptions and .syzprog for programs

Standardizing file extensions will also potentially allow adding syntax highlighting on Github.

I don't mind adding recognizable extensions, but also don't consider it as important enough to work on this myself right now ;)

.prog looks too generic and not syzkaller-specific. I think programs should be .syz because they are more widely distributed with bug reports and used by wider audience, so it makes sense to have shorter/nicer extension for them.

Descriptions are only located in syzkaller sources and used by syzkaller contributors. .syzlang feels a bit long on my taste, but I can't think of anything better... probably it's a fine description.

Another idea: szp for programs and szl for syzlang. Both are short and unique. However, less recognizable.

I also don't have plans to work in this, at least in the foreseeable future. Maybe someone will step in.
