616d068f0c s3: VFS: Modify SMB_VFS_GET_NT_ACL to take a const struct smb_filename * instead of const char *
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.

c5ad5029fd More for #9374 - Allow smb2.acls torture test to pass against smbd with a POSIX ACLs backend.
Change can_delete_directory() to can_delete_directory_fsp(), as
we only ever call this from an open directory file handle.

This allows us to use OpenDir_fsp() instead of OpenDir().
OpenDir() re-checks the ACL on the directory, which may
refuse DIR_LIST permissions. OpenDir_fsp() does not. As
this is a file-server internal check to see if the directory
actually contains any files before setting delete on close,
we can ignore the ACL here (Windows does).

c8ade07760 smbd: Add mem_ctx to {f,}get_nt_acl VFS call
This makes it clear which context the returned SD is allocated on, as
a number of callers do not want it on talloc_tos().

As the ACL transformation allocates and then no longer needs a great
deal of memory, a talloc_stackframe() call is used to contain the
memory that is not returned further up the stack.

e80ceb1d73 Remove more uses of "extern struct current_user current_user;".
Use accessor functions to get to this value. Tidies up much of
the user context code. Volker, please look at the changes in smbd/uid.c
to familiarize yourself with these changes as I think they make the
logic in there cleaner.

Cause smbd/posix_acls.c code to look at current user context, not
stored context on the conn struct - allows correct use of these
function calls under a become_root()/unbecome_root() pair.
