mod_http_file_share: Improve debug logging around unexpected file sizes These didn't have any debug logging and it can be confusing that the "file too large" is also used for a cut-off chunked upload. Not sure if it is worth it to double those checks into > and < just for this.

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;
};
