Add strlen() and strnlen() to commonlib/bsd by rewriting them from scratch, and remove the same functions from coreboot and libpayload. Note that in the existing libpayload implementation, these functions return 0 for NULL strings. Given that POSIX doesn't require the NULL check and that other major libc implementations (e.g. glibc [1]) don't seem to do that, the new functions also don't perform the NULL check.
