    Clean up stack checking code
    
    Several small improvements of the stack checking code:
    - move the CPU0 stack check right before jumping to the payload
      and out of hardwaremain (that file is too crowded anyways)
    - fix prototype in lib.h
    - print size of used stack
    - use checkstack function both on CPU0 and CPU1-x
    - print amount of stack used per core
