6fb98f70c6 ndr: always attempt ACE coda pull if ACE type suggests a coda
We were skipping the pull in cases where the coda size was calculated
to be zero. This has the right result for empty conditional ACEs, but
not for Resource Attribute ACEs where the
CLAIM_SECURITY_ATTRIBUTE_RELATIVE_V1 coda was not intialised.

The situation is made a bit worse, because the function that
calculates the coda size (ndr_subcontext_size_of_ace_coda()) can
return zero in conditions that are not exactly errors, but in which
the would-be calculated value makes so little sense that zero is
thought to be a safer default.

2a60ec9840 ndr: do not push ACE->coda.ignored blob
From 1e80221b23 (2008) until
c73034cf7c (conditional ACEs, etc, 2023)
we had a manual ndr_pull_security_ace() that would discard trailing
bytes, which are those bytes that we now call the coda. The ACE types
that we handled then are those that end up with a coda.ignored data
blob.

With this we effectively restore the long-standing behaviour in the
event that we push and pull an ACE -- though now we discard the
ignored bytes on push rather than pull.

This change is not because the trailing bytes caused any problems (as
far as is known), but because it is much faster to not do the push.

It may be that such ACEs no longer occur.

ac0c8ee01e ndr: short-circuit ace coda if no bytes left
The overwhelmingly common case is that there are no bytes left, and
regardless of the ACE type we want to store an empty blob.

We know the blob will be empty if there are no bytes, so we don't need
to allocate a sub-ndr and tokens list and so forth.

This can save almost half the time of a security descriptor pull.
