c7803b05f7 smb3: fix ksmbd bigendian bug in oplock break, and move its struct to smbfs_common
Fix an endian bug in ksmbd for one remaining use of
Persistent/VolatileFid that unnecessarily converted it (it is an
opaque endian field that does not need to be and should not
be converted) in oplock_break for ksmbd, and move the definitions
for the oplock and lease break protocol requests and responses
to fs/smbfs_common/smb2pdu.h

Also move a few more definitions for various protocol requests
that were duplicated (in fs/cifs/smb2pdu.h and fs/ksmbd/smb2pdu.h)
into fs/smbfs_common/smb2pdu.h including:

- various ioctls and reparse structures
- validate negotiate request and response structs
- duplicate extents structs

be13500043 smb3: move defines for query info and query fsinfo to smbfs_common
Includes moving to common code (from cifs and ksmbd protocol related
headers)
- query and query directory info levels and structs
- set info structs
- SMB2 lock struct and flags
- SMB2 echo req

Also shorten a few flag names (e.g. SMB2_LOCKFLAG_EXCLUSIVE_LOCK
to SMB2_LOCKFLAG_EXCLUSIVE)

15e7b6d753 smb3: move defines for ioctl protocol header and SMB2 sizes to smbfs_common
The definitions for the ioctl SMB3 request and response as well
as length of various fields defined in the protocol documentation
were duplicated in fs/ksmbd and fs/cifs.  Move these to the common
code in fs/smbfs_common/smb2pdu.h

113be37d87 [smb3] move more common protocol header definitions to smbfs_common
We have duplicated definitions for various SMB3 PDUs in
fs/ksmbd and fs/cifs.  Some had already been moved to
fs/smbfs_common/smb2pdu.h

Move definitions for
- error response
- query info and various related protocol flags
- various lease handling flags and the create lease context

to smbfs_common/smb2pdu.h to reduce code duplication

351a59dace cifs: fix bad fids sent over wire
The client used to partially convert the fids to le64, while storing
or sending them by using host endianness.  This broke the client on
big-endian machines.  Instead of converting them to le64, store them
as opaque integers and then avoid byteswapping when sending them over
wire.

0d35e382e4 cifs: Create a new shared file holding smb2 pdu definitions
This file will contain all the definitions we need for SMB2 packets
and will follow the naming convention of MS-SMB2.PDF as closely
as possible to make it easier to cross-reference beween the definitions
and the standard.

The content of this file will mostly consist of migration of existing
definitions in the cifs/smb2.pdu.h and ksmbd/smb2pdu.h files
with some additional tweaks as the two files have diverged.

This patch introduces the new smbfs_common/smb2pdu.h file
and migrates the SMB2 header as well as TREE_CONNECT and TREE_DISCONNECT
to the shared file.
