Now that we have everything in a C file, we can store the information
about our sleep, and have a native mechanism to wake up the sleeping
core. This mechanism would however only wake up a core that's sleeping
while monitoring - waking up from `rte_power_pause` won't work.

Notes:
    v16:
    - Improve error handling
    - Take a lock before UMONITOR

    v13:
    - Add comments around wakeup code to explain what it does
    - Add lcore_id parameter checking to prevent buffer overrun
