Add an aditional (void *) arg to the RMT callback (much like Ticker() et.al.). (#3345)

Browse Source 
* Add an aditional (void *) arg to the RMT callback - to allow more flexible handling of the callback (e.g. by passing a private struct or a class pointer). Same pattern as used by the Ticker() and many others. Example updated & new example with a trapoline added.

* Fix example for new API

* Fix lint warnings

* Add a second missed example.

* Correct timeout & improve socket error handling.
