util.stanza: Support the 'by' attribute on errors This is to be used when the entity generating the error is not the same as the one the stanza was directed to, e.g. an intermediate server.

local xpcall = xpcall;

if select(2, xpcall(function (x) return x end, function () end,  "test")) ~= "test" then
	xpcall = require"util.compat".xpcall;
end

return {
	xpcall = xpcall;
};
