/**
 * Checks whether the given path is secure for use by a root process.
 * This is done by checking whether the path itself, as well as any of the
 * parent directories, can only be written to by root. Returns whether the
 * path is deemed secure.
 *
 * If a non-root user can write to any of the directories in the path then that
 * user can cause the root proces to read an arbitrary file. That file can even
 * be one that is not owned by said user, through the use of symlinks.
 *
 * Checking is done according to normal Unix permissions. ACLs and systems like
 * SELinux are not taken into consideration. Also, if this function fails to
 * check a part of the path (e.g. because stat() failed) then this function
 * simply skips that part. Therefore this function does not perform a full check
 * and its result (which *can* be a false positive or a false negative) should be
 * taken with a grain of salt.
 *
 * Error messages that can be used to inform the user which parts of the path
 * are insecure, are outputted into `errors`. This vector becomes non-empty
 * only if result is false.
 *
 * Any errors that occur w.r.t. checking itself (e.g. stat() errors) are
 * outputted into `checkErrors`. This vector may become non-empty no matter
 * the result.
