We need to migrate all pathname based VFS calls to use a struct
to finish modernising the VFS with extra timestamp and flags parameters.

Requires a few extra cleanups in calling code.

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.

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.

This ensures the caller knows exactly what the memory lifetime of this
returned object is. This makes the NFSv4 ACL code consistent with the
POSIX and NT ACL code, to avoid supprising developers who have worked
on those other parts of the ACL code.
Most of this patch is adding a memory context to the callers and passing it in.

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.
Andrew Bartlett
This changes from allocation on NULL to allocation on the supplied
memory context.
Currently that supplied context is talloc_tos() at the the final consumer of
the ACL.
Andrew Bartlett
The acl element is changed to be a talloc child, and is no longer one element
longer than requested by virtue of the acl[1] base pointer.
This also avoids one of the few remaining cases of over-allocation of a structure.
Andrew Bartlett
There were some function mismatches in the various GET_NT_ACL modules (some places the fsp parameter has not been removed).

(This used to be commit 221cc5e21e)
this can only be done via fset_nt_acl() using an open
file/directory handle. I'd like to do the same with
get_nt_acl() but am concerned about efficiency
problems with "hide unreadable/hide unwritable" when
doing a directory listing (this would mean opening
every file in the dir on list).
Moving closer to rationalizing the ACL model and
maybe moving the POSIX calls into a posix_acl VFS
module rather than having them as first class citizens
of the VFS.

This makes both of aixjfs2_[f]get_nt_acl() more specific,
eliminating the need for aixjfs2_get_nt_acl_common().

Replace smbd/posix_acls.c:get_nt_acl() by two funcions:
posix_get_nt_acl() and posix_fget_nt_acl(). The first
takes a connection struct and a file name instead of a
files_struct pointer. This is in preparation of changing
the vfs api for SMB_VFS_GET_NT_ACL.

BOOL == int). I also need to fix the Samba4 pidl generation

(This used to be commit f35a266b3c)
This adds the two functions talloc_stackframe() and talloc_tos().
* When a new talloc stackframe is allocated with talloc_stackframe(), then
* the TALLOC_CTX returned with talloc_tos() is reset to that new
* frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
* happens: The previous talloc_tos() is restored.
*
* This API is designed to be robust in the sense that if someone forgets to
* TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
* resets the talloc_tos().
The original motivation for this patch was to get rid of the
sid_string_static & friends buffers. Explicitly passing talloc context
everywhere clutters code too much for my taste, so an implicit
talloc_tos() is introduced here. Many of these static buffers are
replaced by a single static pointer.
The intended use would thus be that low-level functions can rather
freely push stuff to talloc_tos, the upper layers clean up by freeing
the stackframe. The more of these stackframes are used and correctly
freed the more exact the memory cleanup happens.
This patch removes the main_loop_talloc_ctx, tmp_talloc_ctx and
lp_talloc_ctx (did I forget any?)
So, never do a
tmp_ctx = talloc_init("foo");
anymore, instead, use
tmp_ctx = talloc_stackframe()
:-)
