When the native os in sessionsetup is "Unix" then broken Konica Minolta
printers refuse to talk to those CIFS servers. Other CIFS servers also announce
themselves with native os Windows. Let's do the same to improve
interoperability with broken devices like those printers from Konica Minolta.
Thanks to Daniel Hoffmann for finding and reporting this Konika printer
brokenness.

This fixes a bug in dfs_samba4 identified by Daniel Müller.
create_conn_struct calls SMB_VFS_CONNECT which requires root privileges.
SMB_VFS_CONNECT in turn calls dfs_samba4_connect which connects to samdb.
Calls were made to this function without ever becoming root (notably via setup_dfs_referral)
which resulted in an error and the VFS connect failing. This happens when you have an active
directory domain controller with host msdfs = yes in smb.conf and dfs links in place.

If we set a non-null 'old timestamp' in the share mode database
when creating a directory handle, this prevents mtime (write time)
updates from being seen by clients, as we will always return the
timestamp stored in the database whilst the handle is open.
For files this is ok, as we update the stored timestamp
ourselves when we write to the handle. For directories
we should just rely on the mtime value from the underlying
filesystem.
Torture test to follow.

Going via tevent_req_create/talloc_free at multiple layer costs
too much cpu cycles per request.
I tested downloading a 16GB (sparse) file with smbclient -b1 -mNT1,
and -mSMB2_02. Using smb2 max read = 64512, which means smb1 and smb2
will use the same read size.
I build with -O3 -g and compared the results with valgrind --tool=callgrind.
With -mNT1 the server uses about 2.000.000.000 cpu cycles.
This patch reduces the userspace cpu cycles for -mSMB2_02
from about ~ 8.000.000.000 down to ~ 4.000.000.000.

This is a performance improvement for heavily contended files, in
particular in a cluster. The separate call to get_file_infos makes us
pull the locking.tdb record twice per open. For a contended file this
can be a performance penalty, this gets the # of record accesses for
the open/close cycle down from 3 to 2.

The VFS interfaces are sychronous, as the operations only modify
meta-data.
These hooks are dependent on support for transparent compression by the
underlying filesystem - vfs_default returns INVALID_DEVICE_REQUEST.
Support for other filesystems providing transparent comression, such as
Btrfs and ZFS, can be added in future.
The get_compression function takes fsp and smb_fname arguments. The
smb_fname argument is needed due to the current dosmode() code-path.
