tevent_req_nomem is to be used in a sequence of async actions where we
have one main request. This is a completely independent loop without one
central tevent_req. tevent_req_nomem is used as a simple way to signal
an out of memory condition to the main request representing the async
sequence. If we don't have such a tevent_req, we need to directly check
for NULL.

FSCTL_SRV_COPYCHUNK can only be used when the client has the copy-chunk
target file open with FILE_WRITE_DATA and FILE_READ_DATA.
FSCTL_SRV_COPYCHUNK_WRITE requires only FILE_WRITE_DATA access on the
target, and is therefore suitable for cp --reflink, which opens the
target file O_WRONLY.

This reverts commit 7b70fa1873.
This is a change in behaviour which needs much further investigation

This makes the is_stat_open special case in grant_fsp_oplock_type
redundant because in open_file_ntcreate further up we have already set
oplock_request to NO_OPLOCK for stat opens.

This avoids the question where it could happen that something else but
fsp->oplock_type might be useful as an argument here.

Some lines above we set fsp->oplock_type = e->op_type. I don't see
how this might have changed. This change will unify both callers of
set_file_oplock. In the next step the second parameter to set_file_oplock
will be removed.

remove_oplock is a wrapper around release_file_oplock. This streamlines
the exports of oplock.c a bit.
Reason for this patch: In a later patch I will add functionality to
remove_oplock that is required in close_normal_file as well.

When the ID returned is ID_TYPE_BOTH we must *always* add it as both
a user and a group, not just in the owning case. Otherwise DENY
entries are not correctly processed.
Confirmed by the reporter as fixing the problem.

Now that we transmit the level we want to break to via the msg.op_type
we can unify MSG_SMB_BREAK_REQUEST and MSG_SMB_ASYNC_LEVEL2_BREAK and
thus simplify the code a bit.

The level we have to break to depend on the breakers create_disposition:
If we overwrite, we have to break to none.
This patch overloads the "op_type" field in the break message we send
across to the smbd holding the oplock with the oplock level we want to
break to. Because it depends on the create_disposition in the breaking
open, only the breaker can make that decision. We might want to use
a different mechanism for this in the future, but for now using the
op_type field seems acceptable to me.

There's no reason why we should not do this. This has turned into a pure
internal consistency check that should apply fine every time.

While refactoring find_oplock_types to validate_oplock_types I forgot
that stat opens will end up in locking.tdb. So even with a batch oplock
around we can have more than one entry. This means the consistency check
in validate_oplock_types was wrong and too strict.

When listing all ranges with "net idmap get ranges", the database records
of the form "S-1-5-10" --> "GID 100016" were treated here as rangee mapings,
resulting in an faulty printout like this: "RANGE 541346119: S-1-5-10".
This patch fixes this by adding a filter that checks the size of the
value datablob.
