random.4: Provide a more accurate description of /dev/urandom

This documents the "property" of /dev/urandom of being able to
serve numbers prior to pool being initialized, and removes any
suggested usages of /dev/random which are disputable
(i.e., one-time pad).  Document the fact /dev/random is only
suitable for applications which can afford indeterminate delays
since very few applications can do so.  Smooth the alarming
language about a theoretical attack, and mention that its
security depends on the cryptographic primitives used by the
kernel, as well as the total entropy gathered.
