s3: libsmbclient: Work around bugs in SLES cifsd and Apple smbx SMB1 servers.
SLES's cifsd and Apple's smbx do not correctly handle FILE_NON_DIRECTORY_FILE
which prevents recursive copies in gvfs from working correctly [1] since GVFS
tries to open the directory, expecting ENOTDIR, but it suceeds and appears as a
zero byte file.
This fix adds code to the cli_open() open code that checks if
CreateOptions was requested with FILE_NON_DIRECTORY_FILE set,
and if the attributes returned include FILE_ATTRIBUTE_DIRECTORY
we synchronously close the file handle just opened, and return
NT_STATUS_FILE_IS_A_DIRECTORY to the caller.
Depends on the previous API update to cli_ntcreate()
to add returned attributes.
Fixes bug #10587 - Opening directories on SLES's cifsd and Apple's smbx succeeds.
