Have err_printf respect log_level #233

Closed rundel closed 5 years ago

Currently if I want to use something like servr:::port_available, on a failure I will always get an error message from createTcpServer:

s = httpuv::startServer("0.0.0.0", 5000, list())
servr:::port_available(5000L, "0.0.0.0")
## createTcpServer: address already in use
## [1] FALSE

in a function like this, this kind of failure is expected so it would be nice if it were possible to suppress these messages temporarily via logLevel("OFF").
