Yukihiro "Matz" Matsumoto b7b06a0857 mruby-task: implement posix hal for timer and interrupt control ...

add hardware abstraction layer with posix implementation:
- setitimer: generates periodic sigalrm for tick-based scheduling
- signal handler: calls mrb_tick on each timer interrupt
- sigprocmask: enables/disables interrupts by blocking sigalrm
- usleep: idle cpu implementation for posix platforms

the hal is initialized during gem init and starts the periodic
timer automatically. non-posix platforms get stub implementations.

tick period is configurable via MRB_TICK_UNIT (default 4ms).
