  Log:
  o Replace calls to p_can(..., P_CAN_xxx) with calls to p_canxxx().
    The p_can(...) construct was a premature (and, it turns out,
    awkward) abstraction.  The individual calls to p_canxxx() better
    reflect differences between the inter-process authorization checks,
    such as differing checks based on the type of signal.  This has
    a side effect of improving code readability.
  o Replace direct credential authorization checks in ktrace() with
    invocation of p_candebug(), while maintaining the special case
    check of KTR_ROOT.  This allows ktrace() to "play more nicely"
    with new mandatory access control schemes, as well as making its
    authorization checks consistent with other "debugging class"
    checks.
  o Eliminate "privused" construct for p_can*() calls which allowed the
    caller to determine if privilege was required for successful
    evaluation of the access control check.  This primitive is currently
    unused, and as such, serves only to complicate the API.
