If a session expires during a compound request chain,
we exit smbd_smb2_request_dispatch() with
'return smbd_smb2_request_error(req, ...)' before
calling smbd_smb2_request_dispatch_update_counts().
As req->request_counters_updated was only reset
within smbd_smb2_request_dispatch_update_counts(),
smbd_smb2_request_reply_update_counts() was called
twice on the same request, which triggers
SMB_ASSERT(op->request_count > 0);

The implementation of group policy apply should
not be in the application script. One reason is
to implement user apply, we can call these
functions via the python c-api, (passing creds
via the command line will expose them via ps).
Another reason for this is if some overrides
the smb.conf "gpo update command" option, it
would be useful to have these functions.

According to MS-FSA a stream name does not have
separate DOS attribute metadata, so we must return
the DOS attribute from the base filename. With one caveat,
a non-default stream name can never be a directory.
As this is common to all streams data stores, we handle
it here instead of inside all stream VFS modules.
Otherwise identical logic would have to be added to
all streams modules in their [f]get_dos_attribute_fn()
VFS calls.

When returning the stat struct for an xattr stream,
we originally base the st_ex_mode field on the value
from the base file containing the xattr. If the base
file is a directory, it will have S_IFDIR set in st_ex_mode,
but streams can never be directories, they must be reported
as regular files.
The original code OR'ed in S_IFREG, but neglected to
AND out S_IFDIR.
Note this is not a complete to fix bug 13380 as
it doesn't fix the generic case with all streams
modules. See later fix and regression test.
