options: change how option range min/max is handled 

Before this commit, option declarations used M_OPT_MIN/M_OPT_MAX (and
some other identifiers based on these) to signal whether an option had
min/max values. Remove these flags, and make it use a range implicitly
on the condition if min<max is true.

This requires care in all cases when only M_OPT_MIN or M_OPT_MAX were
set (instead of both). Generally, the commit replaces all these
instances with using DBL_MAX/DBL_MIN for the "unset" part of the range.

This also happens to fix some cases where you could pass over-large
values to integer options, which were silently truncated, but now cause
an error.

This commit has some higher potential for regressions.
