manual: Update documentation of strerror and related functions
The current implementation of strerror is thread-safe, but this has implications for the lifetime of the return string. Describe the strerror_l function. Describe both variants of the strerror_r function. Mention the lifetime of the returned string for strerrorname_np and strerrordesc_np. Clarify that perror output depends on the current locale.
