[PATCH 0/3] fix up some recent proc fallout and more

From: Mateusz Guzik <mjg_at_freebsd.org>

Patches in this series fix a bug introduced in r280130 and deal with
additional issues.

I'm not happy with how sutff is being done at the moment. In particular
we zero out various fields on process exit, which puts it into a state
state which is not guaranteed when we deal when it is first allocated.
But I guess we can leave it as it is for now.

I don't believe we have a good solution at the moment which would poison
memory returned by uma_zalloc, that would definitely make the issue
apparent right of the bat. Adding such a feature sould be reasonably
simple but fallout may take some time to deal with, I'll make a follow
up thread.

  fork: assign refed credentials earlier
  cred: add proc_set_cred_init helper
  proc: use MTX_NEW flag in proc_init
