misc: minor bugs and comments

sprinkle a little bit of commenting throughout the codebase.  hopefully
i dont regret what i've written

- clone: bottom of stack is passed through
- print: write newline at end of message
- initcall: functions return void type

very basic net startup.  hopefully i dont regret implementing the
websocket protocol myself in a language as holy as C.
