 Log Message:
 arc4random(3): Add automatic tests.
 
 This verifies that:
 - arc4random zeroes its state and reseeds itself on fork
 - arc4random reseeds itself on entropy consolidation (e.g., VM clone)
 - arc4random falls back to global state if it can't allocate local
   state because address space limits cause mmap to fail
 
 NOTE: This adds a new libc symbol __arc4random_global, but it's in
 the reserved namespace and only used by t_arc4random, so no libc
 minor bump.
