A few functions in oplocks_onefs.c need to be accessed from the onefs
vfs module. It would be ideal if oplocks were implemented at the vfs
layer, but since they aren't yet, a new header is added to
source3/include to make these functions available to the onefs vfs
module. oplocks_onefs.o doesn't need to be linked into the onefs vfs
module explicitly, since it is already linked into smbd by default.

Updates the onefs vfs module to add configurable behavior to deal
with sids that are unknown to us. The best examples are aces that
come from robocopy/xcopy.
Adds the following share level options (which are specific to the vfs_onefs
module):
onefs: ignore unmappable sids (Default = false)
If this option is set to true, sids which could not be resolved to
a uid/gid are ignored. If an unmappable sid is encountered as the owner
or group, the owner/group is converted to BUILTIN\Administrators.
onefs: unmappable sids ignore list (Default = empty)
Only the sids in the list are ignored.
onefs: ignore sacls (Default = false)
SACLs are ignored
onefs: unmappable sids deny everyone (Default = false)
If an unmappable sid is found in a deny ACE, the ACE's identity is
changed to Everyone.

This is the first pass at extending the onefs vfs module to support
the CIFS-specific enhancements available on OneFS. Most of this patch
is massaging the sama open path to work with ifs_createfile.
ifs_createfile is a CIFS-specific syscall for opening/files and
directories. It adds support for:
- Full in-kernel access checks using a windows access_mask
- Cluster-coherent share mode locks
- Cluster-coherent oplocks
- Streams
- Setting security descriptors at create time
- Setting dos_attributes at create time
This patch does not implement the samba side of the streams support or
oplocks support. Tests that expect oplocks to be granted or streams
to be supported will fail. This will be remedied in upcoming patches.
