Dirk O. Kaar 482516e393 Minimize header use, move Ticker function definitions into cpp file (#6496)
* Backport from ESP32

* Use new library layout (.../src)

* Cleanup test case.

* C++ style cast required.

* Whitespace

* Inlining via header has better baseline ROM footprint.

* Reordered functions for better code-compare to master

* Reduces ROM footprint some more.

* Avoid unnecessary parameter passing - refactoring, same generated footprint.

* Reformat example sources

/*
Passing paramters to Ticker callbacks
Apart from void(void) functions, the Ticker library supports
functions taking one argument. This argument's size has to be less or
equal to 4 bytes (so char, short, int, float, void*, char* types will do).
This sample runs two tickers that both call one callback function,
but with different arguments.
The built-in LED will be pulsing.
