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

Implement rmtLoop to be able to continuously send pulses (#3650)
Number of pulses is limited to the reserved RMT memory for the channel. Very useful for PWM, Servo and other repeatable signals.

7b3c1dfd50 Fix inability to use all buffers in RMT (#3512)
With the >= used let's say you have four RMT inputs, each using 2 channels wide for their receive buffer. This is 4*2 = 8 buffers which is the number of hardware buffers (MAX_CHANNELS). But, for the fourth input the starting buffer will be 6 (this is correct, the buffers used for each input are 0-1, 2-3, 4-5, 6-7). But, 6+2 = 8 which  is MAX_CHANNELS. This is valid but the >= would match against it and abort. It is correct to only abort if the value i+j is only greater than MAX_CHANNELS. Thus, a simple one character fix. Delete the equals sign.
