component: Avoid adding to the global stream metatable

This allows component and client connections to be made side-by-side.
Previous to this change, loading this connection module would break the
ability to make client connections, due to overriding stream methods such as
:reopen() and :reset().

A next step would be to share the methods that the two connection modules have
in common.

return {
	pack = function(...) return {n = select("#", ...); ...} end;
	create = function() return {} end;
	move = function (a1, f, e, t, a2)
		a2 = a2 or a1;
		if e >= f then
			local n = (e - f) + 1;
			if t > e or t <= f or a1 ~= a2 then
				for i = 0, n-1 do
					a2[t+i] = a1[f+i];
				end
			else
				for i = n-1, 0, -1 do
					a2[t+i] = a1[f+i];
				end
			end
		end
		return a2;
	end;
