9db3ff2573 smbd: use fsp_get_io_fd() when accessing a file or it's associated metadata
In all places where we access or modify a file or it's associated metadata, we
use fsp_get_io_fd() to fetch the low-level fd from the fsp. This ensures we
don't accidentally use a pathref fsp where the fd would be opened as root on
systems lacking O_PATH.

306783d6f5 lib: modules: Change XXX_init interface from XXX_init(void) to XXX_init(TALLOC_CTX *)
Not currently used - no logic changes inside.

This will make it possible to pass down a long-lived talloc
context from the loading function for modules to use instead
of having them internally all use talloc_autofree_context()
which is a hidden global.

Updated all known module interface numbers, and added a

introduce an option to disable the metadata sync
in case the filesystem handles this correctly the sync can be
skipped, but synchronization of the data that was written can still
be configured (in opposition to the disable flag disabling all
sync operations)

4e3656b8d1 s3: Change SMB_VFS_OPEN to take an smb_filename struct
This was a little messy because of all of the vfs modules I had to
touch.  Most of them were pretty straight forward, but the streams
modules required a little attention to handle smb_filename.  Since the
use of smb_filename enables the vfs modules to access the raw,
over-the-wire stream, a little bit of the handling that was being done
by split_ntfs_stream_name has now been shifted into the individual
stream modules.  It may be a little more code, but overall it gives
more flexibility to the streams modules, while also allowing correct
stream handling.
