Indicate BACKUP_INTENT to vfs_openat(). Why? I have a customer request
who wants to add O_NOATIME in this case to avoid metadata updates when
a backup or virus-checking application comes along.
This does not fully handle BACKUP_INTENT correctly, this would require
become_root() appropriately. We might want to do that later after a
lot of careful security audit, but this patch independently might
already provide some infrastructure for it.

This needs close review. I could not see where we were actually
referencing the original flags in a way that would not be available in
local_flags. The reason for this patch is that I want to pass in
vfs_open_how into open_file(), and the distinction between flags and
local_flags made this significantly harder to understand for me.
The only place where we really used both versions is the DBG_NOTICE in
the last hunk, and this will come back in the next patch.

Move adding O_RDWR before the check for read only shares. I haven't
been able to pass this condition through SMB, but in any case we
should not accidentially open with O_RDWR in the !CAN_WRITE(conn)
case.

We have to return NT_STATUS_OBJECT_NAME_INVALID even if we're not
creating. In fact, we probably should not end up in open_file() if
we're open a Windows file with a wildcard.

ctdb-scripts: Implement failcount handling with thresholds
This can be used for simple failure counting, without restarts, as

ctdb-scripts: Avoid errors for uninitialised counters
Uninitialised counters are treated as 0, but still produce an error.
The redirect to stderr needs to come before the redirect for a missing
counter file.
The seemingly saner alternative of moving it outside the subshell
works when dash is /bin/sh (e.g. on Debian) but does not work when
bash is /bin/sh (e.g. on Fedora).

s4:kdc: Add ‘samba_kdc_entry_pac’ wrapper type
With embedded Heimdal, we can mark a PAC as being trusted (i.e. not
issued by an RODC). This is convenient, as it saves us needing to carry
that information in flags, hoping it isn’t inadvertently lost.
System Heimdal and MIT Kerberos, however, don’t provide a way to mark a
PAC trusted. So we add a new wrapper type, ‘samba_kdc_entry_pac’, that
contains this extra information if ‘krb5_const_pac’ doesn’t contain it
already. As it also stores a pointer to the client entry, the
structure’s lifetime must therefore be carefully managed. Finally, it
keeps track of whether the PAC came across a trust, to know which is
useful in some circumstances.

s4:kdc: Remove device PAC validation
In the first place, this check was only applicable to the Heimdal KDC,
the MIT KDC not having support for compounded authentication. Secondly,
it was redundant, because _kdc_fast_check_armor_pac() would have already
been called to verify the armor ticket; a second round of validation
achieved nothing. And finally, the check was flawed: it checked only
*explicitly* armored PACs, and so would have done nothing for an armored
*AS‐REQ*.
In short, this check was useless; remove it.
