Add some constness to avoid some warnings.
Remove use register keyword.

Un-deprecate od(1): rename the `deprecated' variable to `odmode', remove the
deprecation warning from the utility and manual page. Since this utility
is required by POSIX, it's not likely to be removed any time soon.

This is leading up to the addition of the P1003.1-2001 -s -A -j -N -t options.
