Log Message:
Pull up following revision(s) (requested by tls in ticket #92):
        lib/libc/gen/arc4random.c: revision 1.11
        lib/libc/gen/arc4random.c: revision 1.12
Make arc4random far less greedy for entropy.  Make arc4random actually
implement arc4 when used by threaded programs.
Fix bug in previous: don't reinitialize on every call!  Fix arc4random_buf so 
it actually ever initializes -- a security problem with revisions 1.9 and 1.10.
