vfs_ceph: Implement SMB_VFS_FGET_DOS_ATTRIBUTES to preserve create_time

In order to avoid the dependency on dos attribute for create_time we now
preserve the btime before parsing dos attribute which may update btime
from its value with an old one unless we explicitly reset dos attribute
with new create_time in SMB_VFS_FNTIMES implementation. Therefore have
an implementation for SMB_VFS_FGET_DOS_ATTRIBUTES to save and restore
updated create_time.

source3/smbd: Update timestamps after a successful SMB_VFS_FNTIMES

When an open file handle is used to change timestamps we fail to return
updated values to clients until next open is issued. Unless we fill in
the timestamps subsequent calls like GETINFO cannot see the latest value
causing incorrect results. Therefore copy those timestamp values as soon
as it is set on the backend.

ensure http response doesn't exceed the response max length set by
the client call.

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.

fuzz:fuzz_conditional_ace_blob lets long generated SDDL fail

This can legitimately fail, due to e.g. integers being interpreted as
local attributes due to their position (the original data is complete
nonsense, bravely decompiled by sddl_from_conditional_ace).

In the example found the original begins like

while the SDDL cycled version looks like

and this new interpretation ends up being more than 10000 bytes long,
so the conversion fails.

The SDDL ends up looking like this:
