Subject: [PATCH] Change return value of getentropy() to int 0 for success. 
 Maximum buffersize is enforced strictly, this supplies sufficient entropy
 payload to act as seed material.  Discourage general use of this API, but
 lock down this function name as the go-to for userland PRNG seeding.  Improve
 documentation. ok miod matthew
