get_file_handle_for_metadata() is a new function that
finds an existing open handle (fsp->fh->fd != -1) for
a given dev/ino if there is one available, and uses
INTERNAL_OPEN_ONLY with WRITE_DATA access if not.
Allows open_file_fchmod() to be removed next.

This causes deadlocks which cause smbd to crash if the locking
database has already been locked for a compound operation we
need to be atomic (as in the file rename case).
Ensure INTERNAL_OPEN_ONLY opens are synonymous with req==NULL.
INTERNAL_OPEN_ONLY opens leave a NO_OPLOCK record in
the share mode database, so they can be detected by other
processes for share mode violation purposes (because
they're doing an operation on the file that may include
reads or writes they need to have real state inside the
locking database) but have an fnum of FNUM_FIELD_INVALID
and a local share_file_id of zero, as they will never be
seen on the wire.
Ensure validate_my_share_entries() ignores
INTERNAL_OPEN_ONLY records (share_file_id == 0).

With older Samba versions (4.0.x) the following could happen:
- On account was created on DC1
- It was replicated to DC2
- The connection between the dcs is offline
- The account gets modified on DC2
- The account gets deleted on DC1
- The connection becomes online again
- DC1 replicates the modification from DC2,
this resets the dn to the original value.
'name' and 'cn' are correct (with '\nDEL${GUID}'),
but 'dn' is wrong.
- DC2 replicates the deletion from DC1.
this doesn't include a changed dn as DC1
had a bug.

messaging_read_send/recv was okay for just one handler in the queue. For
multiple handlers it was pretty broken.
A handler that deletes itself as part of the callback (pretty typical use
case...) drops the message for a subsequent handler that responds to the same
message type. In messaging_dispatch_rec we walk the array, however
messaging_read_cleanup has already changed the array. tevent_req_defer_callback
does not help here: It only defers the callback, it does not defer the cleanup
function.
This also happens when a callback deletes a different handler
A handler that re-installs itself in the callback might get a message twice.
This patch changes the code such that only messaging_dispatch_rec adds records
to msg_ctx->waiters, new waiters are put into a staging area first
(msg_ctx->new_waiters). Also messaging_read_cleanup does not move anything
around in msg_ctx->waiters, it only nulls out itself. messaging_dispatch_rec is
changed to cope with this.

The event context here was only specified in the server or admin-tool
context, which does not do network communication, so this only caused
a talloc_reference() and never any useful result.

before making the network call.
