The aim of this new module is to contain code that's parsing ACPI
tables. For now, only parsing of IORT table is implemented (it's
ARM specific table). And since we only need to check whether the
table contains SMMU record, the code is very simplified.
I've followed the specification published here:

When opening a connection, it may be necessary to provide user
credentials, or some additional info (e.g. whether to trust an
ssh key). We have a special API for that: virConnectOpenAuth()
where and additional callback can be passed. This callback is
then called with _virConnectCredential struct filled partially
and it's callback's responsibility to get desired data (e.g. by
prompting user) and store it into .result member of the struct.
But we document the callback behaviour as:
When authentication requires one or more interactions, this callback
is invoked. For each interaction supplied, data must be gathered
from the user and filled in to the 'result' and 'resultlen' fields.
If an interaction cannot be filled, fill in NULL and 0.
Returns 0 if all interactions were filled, or -1 upon error
But there are some buggy callbacks out there, which set:
.result = NULL;
.resultlen = 0;
and return 0. Report an error when such buggy callback is met.

Technically, there's nothing libnuma specific about
virNumaNodesetToCPUset(). It just implements a generic algorithm
over virNumaGetNodeCPUs() (which is then libnuma dependant).
Nevertheless, there's no need to have this function living inside
WITH_NUMACTL block. Any error returned from virNumaGetNodeCPUs()
(including the one that !WITH_NUMACTL stub returns) is propagated
properly.
Move the function out of the block into a generic one and drop
the !WITH_NUMACTL stub.

In d9ee51e, virNetDevIPCheckIPv6Forwarding was updated to walk the
contents of /proc/net/ipv6_route so that it could check to see if the
RTF_ADDRCONF was set on any IPv6 routes to ultimately determine if
enabling forwarding would result in an error due to accept_ra=1 being
set on the interface.
The implementation added in that commit limited the number of routes
that could be read from /proc/net/ipv6_route to 100_000, each with 150
characters. This is problematic for machines that have a full IPv6
routing table, as the IPv6 routing table has now grown to over 160_000
(it was closer to 100_000 at the time of that commit).
This patch increases the maximum route size from 100_000 to 1_000_000.
While a million routes is somewhat arbitrary, it's meant to be a value
that can be supported for the forseeable future. APNIC, one of the five
regional internet registries, recently published a forecast of IPv6
table growth which anticipates a worst-case growth to 1_000_000 in
January of 2029.
