Arduino compatibility

Github Repo	C Header	C source	JS source
mongoose-os-libs/arduino-compat	Arduino.h

This library provides a common Arduino compatibility layer, so that one could pick an existing Arduino program, throw it into the Mongoose OS application sources, and ideally, it "just works".

Currently, the following public headers are provided:

• Arduino.h
• Print.h
• WString.h
• stdlib_noniso.h

There are more specific Arduino-compatibility libraries available: for onewire, SPI, etc.
