James Tucker 0f3b2e7b86 util/expvarx: add a time and concurrency limiting expvar.Func wrapper
expvarx.SafeFunc wraps an expvar.Func with a time limit. On reaching the
time limit, calls to Value return nil, and no new concurrent calls to
the underlying expvar.Func will be started until the call completes.
