Mark Johnston 5df40377e7 pf: Make pf_get_translation() more expressive 
Currently pf_get_translation() returns a pointer to a matching
nat/rdr/binat rule, or NULL if no rule was matched or an error occurred
while applying the translation.  That is, we don't distinguish between
errors and the lack of a matching rule.  This, if an error (e.g., a
memory allocation failure or a state conflict) occurs, we simply handle
the packet as if no translation rule was present.  This is not
desireable.

Make pf_get_translation() return the matching rule as an out-param and
instead return a reason code which indicates whether there was no
translation rule, or there was a translation rule and we failed to apply
it, or there was a translation rule and we applied it successfully.
