since we moved our signal handlers to be created before subsystems are
created, our new signal handlers (which namely blocks SIGTERM, used for
panicing) are passed on. in order to restore full panic functionality,
we clear all signal blocks before passing execution to the subsystem

(log)
- create LOGLEVEL constant numbers
- implement CONSOLE_LOGLEVEL
- color array now uses loglevel constants
- timestamp now shown (thanks util-linux)
(init)
- register mainpid
- hello world print
- fix process reaper to refer to subsys when reaping
(subsys)
- create maximum subsystem count
- create subsystem table
- add debugging prints to subsystem entry and termination
- create function to handle process termination (unmap stack, free
subsystem malloc, clear entry in table)
- disable subsystem inception
- change die references to fail with print
- supply clone with signal to send on termination (SIGCHLD)

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.

- create subsystem system using clone syscall, shared memory, shared
file descriptors
- printk-like logging facility (TODO: console loglevel)
- initcall system (like linux kernel)
TODO: determine license
factors: linker.ld, linux kernel licensing (some ideas are more
liberally taken rather than paraphrased)
