Add a new function, get_claims_set_for_principal(), that returns the
claims as a CLAIMS_SET structure rather than as a blob. To accommodate
this, move the call to encode_claims_set() out of get_all_claims() and
into get_claims_blob_for_principal().
Being able to get the unencoded claims will save us from having to
decode claims that we just needlessly encoded.

Wrapping a function this simple doesn’t gain us very much.

As the server authentication policy will be non-NULL only for entries
looked up as servers, the krbtgt shouldn’t have an authentication policy
anyway. But we might as well be explicit.

This function doesn’t require a heap allocation.
We also check the result of the function, which we weren’t doing before.

This change ultimately won’t make much difference to responses, as
unrecognized codes are mapped to ERR_GENERIC in any case. But it might

If we’re going to zero the keys before freeing them, we might as well do
it properly.

If we exited this function early due to an error, h->len would contain
the number of elements that *ought* to be in h->val, but not all of
those elements must have been initialized. Subsequently trying to free
this partially-uninitialized structure with free_Keys() could have bad
results.
Avoid this by ensuring that h->len accurately reports the actual number
of initialized elements.

To these conversion functions we sometimes pass malloc-allocated HDB
structures, which we free afterwards if conversion fails. If parts of
these structures are still uninitialized when we try to free them, all
sorts of fun things can result.

Use a temporary context to allocate these variables. Each variable that
needs to be transferred to the caller is stolen onto an appropriate
talloc context just prior to the function’s returning.
