cli_smb2_list() appears to be a slightly unique SMB operation in that it
specifies the max transaction size for the response buffer size. The
Python bindings highlighted a problem where if cli_smb2_list() were one
of the first operations performed on the SMBv2 connection, it would fail
due to insufficient credits. Because the response buffer size is
(potentially) so much larger, it requires more credits (128) compared
with other SMB operations.
When talking to a samba DC, the connection credits seem to start off at
1, then increase by 32 for every SMB reply we receive back from the
server. After cli_full_connection(), the connection has 65 credits. The
cli_smb2_create_fnum() in cli_smb2_list() adds another 32 credits, but
this is still less than the 128 that smb2cli_query_directory() requires.
This problem doesn't happen for smbclient because the cli_cm_open() API
it uses ends up sending more messages, and so the connection has more
credits.
This patch changes cli_smb2_list(), so it requests a smaller response
buffer size if it doesn't have enough credits available for the max
transaction size. smb2cli_query_directory() is already in a loop, so it
can span multiple SMB messages if for some reason the transaction size
isn't big enough for the listings.

The current implementation of `rmdir` hopes to get the directory deleted
on closing last open handle when FILE_DELETE_ON_CLOSE is set on it. But
for non-empty directories Windows doesn't error out during an open call.
Following that we internally refuse to set initial delete_on_close while
opening a non-empty directory. This prevents us from trying to delete
the directory when last open handle is closed.
Instead of relying on FILE_DELETE_ON_CLOSE during an open we explicitly
set delete_on_close token on directory handle once it is available. This
ensures that NT_STATUS_DIRECTORY_NOT_EMPTY is returned for `rmdir` on
non-empty directories while closing open directory handle.

ndr_size_dom_sid returns a size_t, so that can't be <0. Also, the only
case that ndr_size_dom_sid returns 0 is a NULL sid
pointer. ndr_size_dom_sid can reasonably be assumed to not overflow, the
number of sub-auths is a uint8. That times 4 plus 8 always fits into a
size_t.

We have to do the parsing manually. Looking at librpc/gen_ndr/ndr_notify.c we
have the following code snippet:
size_FileName1_0 = strlen_m(r->FileName1);
NDR_CHECK(ndr_pull_charset(ndr, NDR_SCALARS, &r->FileName1,
size_FileName1_0, sizeof(uint16_t),
CH_UTF16));
which means that we take strlen_m(r->FileName1) before we pull
it off the wire. Not sure how to fix this, but that is clearly
broken pidl output. Once that is fixed, we can convert this
to ndr_pull_struct.

SMB1 uses attr == 0 to clear all attributes
on a file (end up with FILE_ATTRIBUTE_NORMAL),
and attr == FILE_ATTRIBUTE_NORMAL to mean ignore
request attribute change.
SMB2 uses exactly the reverse. Unfortunately as the
cli_setatr() ABI is exposed inside libsmbclient,
we must make the SMB2 cli_smb2_setatr() call
export the same ABI as the SMB1 cli_setatr()
which calls it. This means reversing the sense
of the requested attr argument if it's zero
or FILE_ATTRIBUTE_NORMAL.
