David Thornley da0226fa7e lua: Fixed broken __lt/__le operators caused by lnum patch.
This was found while investigating why luarocks does not work. It was
traced to a quite old lnum patch for 5.1.3. I compared against the
latest 5.1.4 patch - https://github.com/LuaDist/lualnum and discovered
the lessthan/lessequal evaluation was not falling through to the
call_orderTM (tag methods).

I have tested LuCI (simple tests) and used the following lua code to
validate the patch (both host and target patches supplied): -

> local my_mt = {
> __eq = function(v1, v2)
> print("__eq")
> return false
> end,
> __lt = function(v1, v2)
> print("__lt")
> return false
> end,
> __le = function(v1, v2)
> print("__le")
> return false
> end
> }
>
> function get_my(vstring)
> local my = {}
> my.string = vstring;
> setmetatable(my, my_mt);
> return my;
> end
>
> local a = get_my("1.0")
> local b = get_my("1.0")
>
> local eq_works = a == b;
> local lt_works = a < b;
> local gt_works = a > b;
>
> local lte_works = a <= b;
> local gte_works = a >= b;

Without the patch the following error will be presented: -

“attempt to compare two table values”
