* 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
