options: remove CONF_TYPE_POSITION

This was the option parser for the off_t C type. These days, off_t is
always int64_t, so replace all its uses by int64_t and CONF_TYPE_INT64.

Fix the --sstep option. It used CONF_TYPE_INT with an off_t variable,
which will result in invalid memory accesses. Make it use type double
instead, which seems to make more sense for this option.
