Number CPUs from zero by default.

Browse Source 
Numbering from one is idiosyncratic and inconsistent with basically
everything else in the world; it doesn't make much sense as default
behavior.

All naming is updated to reflect that numbering from one is a
non-default, opt-in option.  The old label of the flag saved in htoprc
("cpu_count_from_zero") is still supported for backwards compatibility
with existing configs, however.
