An analyzer to detect uses of the default http.ServeMux in Go programs
Serving traffic with the default http.ServeMux has some risks! If anything you import calls http.Handle(), it will get served on the same port as your application.
In particular, importing net/http/pprof registers things on the default ServeMux.
This linter tries to help avoid that by flagging uses of http.Handle() and http.HandleFunc(), calling ListenAndServe() with a nil Handler argument, or creating an http.Server with a nil Handler argument.
