$cvar could be an expression such as ‘1 << 10’. In such cases this cast
presumably was intended to apply to the entire expression, not just to
the ‘1’.

If ‘int’ is a 32‐bit type, then 1 << 31 cannot be represented in an
‘int’, and this shift will invoke undefined behaviour.
We have got away with this so far because of a Pidl bug that changed the
expression to ‘(uint32_t)1 << 31’, which is valid. But that bug is about
to be fixed.

Pidl will generate code like the following:
py_out_2 = PyLong_FromLong((uint16_t)*r->out.out[out_cntr_2]);
As the array subscripting operator has a higher precedence than the
indirection (derference) operator, the argument will be evaluated as
(uint16_t)*(r->out.out[out_cntr_2]), which is wrong.
Fix Pidl to generate the following code instead:
py_out_2 = PyLong_FromLong((uint16_t)(*r->out.out)[out_cntr_2]);

It is easier for external callers to manipulate the krb5_get_init_creds_opt
(via the helpers) as this is passed down from higher up than the krb5_init_creds_context.
And just as importantly, alignment with MIT makes end-user callers happier.
Finally, this resolves the ambiguity as to which layer owns the
krb5_ccache, because now we match the MIT behaviour the init_creds code
re-opens a private copy inside libkrb5, meaning the caller closes the
cache it opened, rather than handing it over to the library.
(The unrelated changes are fixes to the test_pac test, also included in this import,
but in distinct lorikeet-heimdal commits, to allow it to compile)

If the number of members does not match in certain ways we can
say the sets are not equal without comparing the members.
We first need to check for comparability, though, so that we can return
an error if things aren't comparable.

We had the comparison method wrong. Composites are compared as sets or
flabby sets, depending on their origin. Until now we compared them as
something a bit like sets, but not quite, in a maximally inefficient way.
Claims are always sets, and the left hand side is always a claim, but
literal composites on the right hand side can be multi-sets
(containing duplicate values). When it comes to comparison, composites
are reduced down to sets. To do the comparison we sort each side and
compare in order.
The fact that either side might ask for case-sensitive comparison (if
it is a claim) is an interesting complication.

For SDDL Resource ACE conversions we don't want to check too much
claim validity so that a semi-invalid ACE can round-trip through
deserialisation and serialisation. This is because Windows allows it,
but also because if the check puts the values in a sorted order that
makes the round-trip less round (that is, the return string is
semantically the same but possibly different in byte order).
The validity we're talking about is mostly uniqueness. For example
`S:(RA;;;;;WD;("foo",TU,0,7,5,7))` has two 7s, and that would be
invalid as a claim, but this is not checked while in ACE form.
On the other hand `S:(RA;;;;;WD;("foo",TU,0,3,2))` is valid, but the
return string will have 3 and 2 reversed when the check is made. We
prefer the ACE to stay the same while it is just being an ACE.

If it is a wire claim (which is probably most common), the checking
and sorting has already happened. We don't need to make a copy to
sort and check.
In either case, there is still a copy step to make the conditional ACE
token.
This shuffles around some knownfails because the claim_v1_copy()
function we were using is checking for duplicates, which we don't
always want. That will be fixed soon.

Because RA ACEs live a double life, sometimes being ACEs and sometimes

We don't need to do that for wire claims, because they are not
persistent or forwarded on to somewhere else.

This roughly returns things to where they were a few commits ago, with
the claims being checked for uniqueness.
The difference is the claims will be sorted afterwards, and the
uniqueness check will be far more efficient on large claims.

To manage this sort we need a qsort_r-like sort context which holds:
a) the value type,
b) a case sensitive flag for the string compare, and
c) a return flag indicating a failure. Failures are not picked up until
after the sort finishes.

claim_v1_check_and_sort() is meant to sort the claim values and check
that there are no duplicates, as well as making some value checks.
In order to ease into the idea, we look first at the case where the claim
has Boolean values. There are only two values allowed, which limits the
length of a valid claim set and means we only really need to "sort" in
the {1, 0} case, which we rewrite in place as {0, 1}.
That's what will happen with other types: we'll sort in-place, make
some checks on values, set flags, and return an error if there are
duplicates or value errors.
