util.set: Change tostring format to {a, b, c} Makes it easier to make out where the set starts and ends in cases where it may get embedded and tostring()-ed in a log message. { } taken over from util.array for consistency with some other systems syntax for Sets, e.g. Python

local xpcall = xpcall;

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

return {
	xpcall = xpcall;
};
