Function to walk all leases for a file exactly once. This used to be simpler
with the leases[] array, thus this function that encapsulates the complexity.

Temporary patch to keep the code running. The new code in set_share_mode() will
leave again once the patchset to remove share_mode_lease and thus the lease_idx
in share_mode_entry goes away.

Instead of indexing into the leases[] array, put the lease_db reference into
the share_mode_entry. For simplicity, put in the client guid as well. We
*might* be able to retrieve that from somewhere else, but as other smbd
processes have to look at the lease values, put in the full leases_db index
data.

Do the rename under one lock to protect against potential races while

Factor out the NDR marshalling into leases_db_do_locked(), leaving the

lock reference count is always increased and reduced by a value of 1.
But lock_ref_count variable holds the old value prior to change and
was being logged wrongly under debug level 10. DEBUG statement must
log lock_ref_count+1 and lock_ref_count-1 respectively when value
gets increased and decreased.

lock_ref_count will always hold the old value prior to change. Thus it
would mean that if lock_ref_count is 0 the new value is already -1 which
is not expected here. Therefore it is better to make sure that it is
