Add support for getenv as defined by the Open Group's "System Interface & Header" in https://pubs.opengroup.org/onlinepubs/7908799/xsh/getenv.html getenv requires a standard way of accessing the environment, so a pointer to the environment is added to the startup in crt1. Consquently, this function is not usable on top of other libcs. Added starts_with method to StringView. getenv function uses it.
