During coredump, dangerous-area-checking should be disabled, and cache disabling should be replaced by a safer version. Dangerous-area-checking used to be in the HAL, but it seems to be more fit to os functions. So it's moved to os functions. Interfaces are provided to switch between os functions during coredump.
