Provide an xxx_opt alternative for functions raising Not_found
and many instances of Failure/Invalid_arg.
The only exception is the rarely used Buffer.add_substitute, where
the [Not_found] can really be interpreted as an error condition.
Most new functions are implemented directly (instead of wrapping the
raising version). This is for performance reasons and also to avoid
destroying the stacktrace (if the function is used in an exception
handler). One could instead implement the raising versions on top of
the new functions, but there might be a small penalty.
Also, add documentation for the US-ASCII variants.

This updates Char, String, Bytes in the stdlib.
For now, they are hidden from documentation and are only for
internal compiler use.
