Previous to this commit we were modifying the offset before
the array offset check. This was causing a spurious debug
message indicating the offset was out of bounds. An second
problem is that upon detecting the error we don't exit the loop.
A third problem was that when reading the offset the check
didn't cater for the size of the integer address about to be read.
This commit moves the offset check to before the first read,
additionally when an error is detected now we actually exit the loop
and the offset have been corrected to include the size of the
integer to be read

Prior to this change fn 'extract_variant_addresses' actually returns offsets
to the variant stored not the addresses, additionally the param in the
signature of the method is named offset where the param in reality is a
base address.
This change makes fn 'extract_variant_addresses' actually return addresses
instead of offsets and also changes the name of the incoming param. The
resulting changes are propaged to callers which hopefully makes what the
code is actually doing a little clearer

(cherry picked from commit efa60ff3105ac80ffff6d2a5d82dd0615ddb7578)
Offset can be a 32 or 64 bit address depending on the indexing addressing
mode negotiated by the client
With a 32 bit param we can only specify a 32 bit base address. This change
alone doesn't affect anything as it is the client itself that choses and
passes the base address offset and wspsearch is the only current user of
this code.
In this case even with 64bit addressing negotiated the address passed
represents only the lower 32-bits part of the address.
However, for coverage purposes it would be better for the client to use an
address that covers the full 64bit range of the address (when 64 bit
addressing is negotiated).
This change will alow the wspsearch client in a future commit to pass a
base address value with both the hi and low 32 bits values set to make up
the full 64 bit address.

The design is relatively simple in the end:
- We use ctdbd_all_ip_foreach() in order to build an
in memory list of interfaces(ip addresses) and
record if:
- they are currently available or not
- if they node local or not
- The current list is would we use for the
GetInterfaceList() call.
- Register[Ex] will create an in memory structure
holding a queue for pending AsyncNotify requests.
- Unregister() will cancel pending AsyncNotify requests and
let them return NOT_FOUND.
- CTDB_SRVID_IPREALLOCATED messages will cause we refresh
with ctdbd_all_ip_foreach():
- this will detect changes in the interface state
and remove stale interfaces.
- for each change the list of registrations is checked
for a matching ip address and a RESOURCE_CHANGE
will be scheduled in the queue of the registration,
the started queue will trigger AsyncNotify responses
- We also register the connections with ctdb in order
to give other nodes a chance to generate tickle-acks
for the witness tcp connections.

This reverts commit 0e3836e3961f2b7c39173ce1023d3c92addef630.
With capabilities preferred over become_root() we failed to achieve
the basic goal of storing NT ACLs in xattrs using vfs_acl_xattr. This
is due to the fact that apart from CAP_DAC_OVERRIDE it is manadatory
to have CAP_SYS_ADMIN for write access to xattrs from security
namespace[1]. Despite the option to configure the xattr name within
the module we should not anticipate and miss to consider xattrs from
security namespace which is far more protected even with our default
name "security.NTACL".
Theorotically we could make it work by adding another capability on
top of existing ones. But given the functions designed around this
area we may not be able to come up with a cleaner change which can
handle the fallback mechanism to become_root(). Any failure to set
the very first capability would put us in become_root() path where
further capabilities are mostly not required. Thus reverting to old
behaviour to always become_root() until we have a cleaner approach
to handle the fallback while modifying multiple capabilities at once.

To make things worse, at that point the new struct netr_DomainTrust is not yet

counter at the start of the loop without initializing it.
Later when NDR-pushing the result in dcesrv_call_dispatch_local(), the ndr_push() can

Deferring assignment of r->out.domains->array and r->out.domains->count to the
end of the function ensures we don't return inconsistent state in case of an
error.
Also, r->out.domains is already set by the NDR layer, no need to create and
assign a struct netr_DomainTrustList object.
Using talloc_move() ensures we don't leave dangling pointers. Better to crash
reliably on accessing NULL, then accessing some unknown memory via a wild
pointer. As talloc_move() can't fail, there's no need to check the return value.
And using a struct initializer ensures all members are properly initialized.
