rename all HAL functions from mrb_<feature>_hal_<name>() to
mrb_hal_<feature>_<name>() for better grouping and clarity. this makes all
HAL functions immediately identifiable with the mrb_hal_* prefix.
affected gems:
- mruby-task: mrb_task_hal_* -> mrb_hal_task_*
- mruby-io: mrb_io_hal_* -> mrb_hal_io_*
- mruby-socket: mrb_socket_hal_* -> mrb_hal_socket_*
- mruby-dir: mrb_dir_hal_* -> mrb_hal_dir_*
