s3/smbd: fix handling of delete-on-close on directories

Browse Source 
This implements a check to test the delete-on-close flag of a directory
for requests to create files in this directory.

Windows server implement this check, Samba doesn't as it has performance
implications.

This commit implements the check and a new option to control it. By
default the check is skipped, setting "check parent directory delete on
close = yes" enables it.

<para>A Windows SMB server prevents the client from creating files in a
directory that has the delete-on-close flag set. By default Samba doesn't
perform this check as this check is a quite expensive operation in Samba.
