The reason for this, apart from weighing up possible over-allocations
vs realloc costs, is in the first iteration of the loop,
claim_values = talloc_array(claims,
would allocate onto NULL, which leaks.

Our composite comparisons are currently all wrong.
Soon they will be fixed, but we are going to have an inflection point
where we switch from the naive compare-everything approach to a sort
based comparison, and we want to test both sides. Also, we use these
tests for a little bit of timing, which reveals it is all fast enough.

The same flag will be used in conditional ACE composites, and on
CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 structures derived from wire
claims and resource attribute ACEs, when we know we have checked the
claim has no duplicate values.
Resource Attribute ACEs contain CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1
at rest, but we are not going to set the flag there on the off chance
that the ACE could fly off to another application and have another
application specific meaning there. We will only check for uniqueness
and set the flag on ephemeral copies of resource claims during access
check operations.

This region is "available for application-specific data" in the

This allows it to align with
CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1.flags, with which it shares
values and will soon share more.
It was 16 bit because we needed few flags, and at one point .type was
8 bit, so 16 bits packed nicely into a smaller struct.

This basically reverts commit b3cae8dcf1
with a few important differences:
* SMB3 UNIX extensions are always built, but disabled by default at runtime.
* They are globally enabled in the fileserver test environment.
* It's now a per-share option, so admins can selectively disable them
on a per-share basis. This allows clients to detect early that a share
doesn't support user mount requested POSIX and fail appropiately, passing
the failure to the requesting application (mount command).

We had two sets of test vectors (Windows ground-truth for SDDL
compilation) that got mixed up.
The "oversized ACLs" set is ACLs that contain repeated ACEs, like
"D:P(D;;;;;MP)(D;;;;;MP)" -- Windows will assign a size to the ACL
that is greater than the sum of the ACEs, while Samba will not (in
part because we don't actually store a size for the ACL, instead
calculating it on the fly from the size of the ACEs).
The "TX integers" set is for resource attribute ACEs with octet-string
data that contains pure integers (lacking '#' characters) in their
SDDL, like «(RA;;;;;WD;("bar",TX,0x0,0077,00,0077,00))». We used to
think that was weird, and that RA-TX ACEs should contain octet-strings
in the conditional ACE style. But now we have realised it's not weird,
it's normal, and we have fixed our handling of these ACEs.
As a result of this mix-up, some of the tests labelled as "oversized
ACLs" started passing when we fixed the TX integer problem, and that
was confusing. All of the removed tests are already on the TX integer
set -- the removed ones were duplicates.

We were reusing parse_literal() because it almost does what we need,
but it is different enough that check_resource_attr_type() is large
and complicated, and can't handle all the cases (in particular octet-
strings and SIDs are different in resource ACEs).
This way is better because we know the type in advance, so we can use
that to choose the parser, which will help with octet-strings that are
only digits.
In this commit we're leaving the check there, but it soon won't do
anything that the parse_* functions don't, and we will remove it.
