commit 14e3cd9f5243ac003d6316da3c7b34911e9e313f
Author: Christopher Collins <ccoll...@apache.org>

    Export basic env vars in newt process
    
    Export the following environment variables in the newt process itself:
    
        "CORE_PATH"
        "BSP_PATH"
        "BIN_ROOT"
        "MYNEWT_PROJECT_ROOT"
        "MYNEWT_NEWT_PATH"
    
    These allows a `pkg.yml` file to use these settings in its list of
    custom commands.
