Clang Format (#514)

* Apply clang-format

* Fixed conflict between "print.h" and <print.h>

print.h and print.cpp are not used.

* machine.h: clang-format off is unnecessary

* ifdef ARDUINO_ARCH_ESP32 is unnecessary

and causes irritiating indentation of other includes

* Revert formatting of nofile.h

But leave pragma changes.

* Fix nofile.h again

* Some files were not formatted ...

and .clang-format needed to be tweaked to
give the same results with clang-format v6 and v10

* clang-format v6 vs v10 compatibility

.clang-format
