Introduce a facility to generate unpredictable 32 bit numbers with
near maximal (2^32) cycle times. These are useful for network
IDs in cases where there are negative consequences to ID prediction
and/or reuse.
Use the idgen32() functions to generate IPv6 IDs and NFS client/server
XIDs.
Pseudorandom permutation code in crypto/idgen.c based on public
domain skip32.c from Greg Rose.
