Kill the use of atoi() and introduce syntax check to forbid it and it's
friends (atol, atoll, atof, atoq).
Also fix a typo in variable name holding the cylinders count of a disk
pool (apparently unused).
examples/domsuspend/suspend.c will need a larger scale refactor as the
whole example file is broken thus it will be exempted from the syntax
check for now.
