If we can access the path to a file, by default we have FILE_READ_ATTRIBUTES
from the containing directory. See the section: "Algorithm to Check Access to an
Existing File" in MS-FSA.pdf.
So it's also safe to use a root opened pathref fd, as the root open is done on
the final component after a chdir() to the parent directory was done while still
impersonating the use. Qed.

Rather than have safe_string.h #include string_wrappers.h, make users of
string_wrappers.h include it explicitly.
includes.h now no longer includes string_wrappers.h transitively. Still
allow includes.h to #include safe_string.h for now so that as many
modules as possible get the safety checks in it.

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
WHATSNEW.

For a posix acl call on a symlink, we've already refused it.
For a Windows acl mapped call on a symlink, we want to follow
it.

This is important, as we need to avoid asking any lower module for a
possible libear ACL blob. We may implement a linearisation in the
future.

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.

Start of the move towards handle-based code for directory access.
Currently makes fstat/fchown code work for directories rather than
falling back to pathnames.

This matches the structure that new code is being written to,
and removes one more of the old-style named structures, and
the need to know that is is just an alias for struct dom_sid.

down to NEXT-> before initializing. This allows us to
do cleanup (by calling DISCONNECT) if initialization
fails. Also fix vfs_acl_xattr which was failing to
call the NEXT connect function.
