* This changes the way policies are reported in audit logs.
Previously, only policies tied to tokens would be reported. This could
make it difficult to perform after-the-fact analysis based on both the
initial response entry and further requests. Now, the full set of
applicable policies from both the token and any derived policies from
Identity are reported.
To keep things consistent, token authentications now also return the
full set of policies in api.Secret.Auth responses, so this both makes it
easier for users to understand their actual full set, and it matches
what the audit logs now report.

A change in copystructure has caused some panics due to the custom copy
function. I'm more nervous about production panics than I am about
keeping some bad code wiping out some existing warnings, so remove the
custom copy function and just allow direct setting of Warnings.
