This is the first step towards setting up nightly builds and automatic library builds for Mbed projects. Because of an issue with Arm's Mbed build system, I had to rename string.h to string_type.h: https://github.com/ARMmbed/mbed-cli/issues/917 This could potentially break clients that look for the particular header, but I don't believe we expect this to be part of the public API, and my internal searches haven't found projects that do this.
