a926d0f461 smbd - allow updates on directory write times on open handles.
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.

4244a2686c s3:smb2_server: for performance reasons we use tevent_fd and readv/writev directly
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.

a793ac016d smbd: Pull mtime handling into open_file_ntcreate
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.

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.
