This is in preperation of modularizing the storage backend. Currently we
store the NFS4 ACL as an IDL/NDR encoded blob in a xattr.
Later commits will add a different backend storing the NFS4 ACL as an
XDR encoded blob in a xattr.

This changes the way ACL inheritance is achieved in this
module.
Previously the module recursed to the next parent directory until the
share root was reached or a directory with an ACL xattr. If the share
root didn't contain an ACL xattr either a default ACL would be used.
This commit removed this recursive scanning and replaces it with the
same mechanism used by vfs_acl_xattr: by setting "inherit acls = yes"
just let smbd do the heavy lefting and inheritance.
For any file without ACL xattr we still synthesize a default ACL,
leveraging the existing default ACL function used by vfs_acl_xattr.

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.

Pure placeholder right now, this will allow vfs modules to load the params
in advance. nfs4 acl parameters should not change while a tcon is live,
and lp_parm_get_* show up in profiles. Loading the parameters once at
tcon time will remove this.

Bumps VFS version to 35.
Preparing to reduce use of lp_posix_pathnames().
Most of this is boilerplate, the only subtleties are in
the modules:
vfs_catia.c
vfs_media_harmony.c
vfs_shadow_copy2.c
vfs_unityed_media.c
Where the path is modified then passed to SMB_VFS_NEXT_GET_NT_ACL().
In these cases the change uses synthetic_smb_fname() to
create a new struct smb_filename from the modified path.

Recursively inherit ACL from parent directory if no acl xattr is
found on the current file.
Use a default ACL if a non-inheriting ACL is encountered.
With this the nfs4acl_xattr.dynamic test passes.
But the nfs4acl_xattr.inheritance test results in an error because
of warnings that cause the test to pass a failed result.
