the ACEs should be talloc children of the ACL itself and not be placed on talloc_tos()

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.

A full fsp is a bit overkill here

While it is possible to define inheritance flags on files on Windows, this will
be denied by GPFS and UFS (and potentially others).
So it will be better to strip of these bits when being set for files instead of
failing to set the ACL completely (this is current behavior).
Users that want to retain the full SD will have to use acl_xattr (acl_tdb), as
other pieces of the SD are also lost when translating to NFSv4. So this should
not be a too intrusive change, but allow users to migrate data with such flags
instead of failing to migrate the ACL completely.
By checking just the IDMAP, and by removing the sidmap and lookup_sid calls, we support
IDMAP_BOTH. This is because by checking for a mapping to a GID first, we can rely on
the fact that IDMAP_BOTH will resolve to a GID.
If the sidmap idea is valued - it allows multiple SIDs to map to a single unix ID, this should
be done in the IDMAP layer.

This will be used to enforce a lock hierarchy between the databases. We have
seen deadlocks between locking.tdb, brlock.tdb, serverid.tdb and notify*.tdb.
These should be fixed by refusing a dbwrap_fetch_locked that does not follow a
defined lock hierarchy.
Thanks to Youzhong Yang for discovering this issue.

Also start new folder lib/dbwrap/ where dbwrap_open.c is stored and
make the fallbacke implementation functoins non-static and create a
dbwrap_private.h header file that contains their prototypes.

we should not merge ACEs with different flags (e.g. CI/OI/I/)
Otherwise ACLs get wrong entries and thus wrong semantics
Example:
ACL:BUILTIN\Users:ALLOWED/0x0/FULL
ACL:BUILTIN\Users:ALLOWED/I/READ
got merged to
ACL:BUILTIN\Users:ALLOWED/I/FULL
This is not the same and also leads to wrong displays
in the Windows ACL dialog

My previous patches fixed up all direct TDB callers, but there are a
few utility functions and the db_context functions which are still
using the old -1 / 0 return codes.
It's clearer to fix up all the callers of these too, so everywhere is
consistent: non-zero means an error.

it inline. Allows us to carefully control what flags
are mapped to what in one place. Modification to

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.

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.
Jeremy.
