Log Message:
Add a new scope, the credentials scope, which is internal to the kauth(9)
implementation and meant to be used by security models to hook credential
related operations (init, fork, copy, free -- hooked in kauth_cred_alloc(),
kauth_proc_fork(), kauth_cred_clone(), and kauth_cred_free(), respectively)
and document it.

Add specificdata to credentials, and routines to register/deregister new
"keys", as well as set/get routines. This allows security models to add
their own private data to a kauth_cred_t.

The above two, combined, allow security models to control inheritance of
their own private data in credentials which is a requirement for doing
stuff like, I dunno, capabilities?
