Some operations like interface creation may need to return metadata
- in this case, interface name - back to the caller if the operation
is successful.
This change implements attaching an `NLMSGERR_ATTR_COOKIE` nla to the
operation reply message via `nlmsg_report_cookie()`.
Additionally, on successful interface creation, interface index and
interface name are returned in the `IFLA_NEW_IFINDEX` and `IFLA_IFNAME
TLVs, encapsulated in the `NLMSGERR_ATTR_COOKIE`.

Currently isolation and resource requirements are handled directly
by the kyua runner, based on the requirements specified by the test.
It works well for simple tests, but may cause discrepancy with tests
doing complex pre-setups. For example, all tests that perform
VNET setups require root access to properly function.
This change adds additional handling of the "require_user" property
within the python testing framework. Specifically, it requests
root access if the test class signals its root requirements and
drops privileges to the desired user after performing the pre-setup.

Use an std::stringstream instead. get_word() and get_quoted_word() both
return a buffer that's presumed to not need release, so solve this by
returning a new special configword type that holds a string or eof/eol
state. This cleans up caller checking for EOF/EOL to make it more
explicit what they're doing, at least in the EOL cases which previously
checked for NULL.

asomers@ found a problem with the NFS client, where a write to
an NFS mounted file done via mmap(2) was lost when fspacectl(2)
was done before it. This turned out to be caused by clearing the
dirty bit on pages when the client was doing commit RPCs,
due to the second argument to vfs_busy_pages() being set to 1.
Commit RPCs tell the server to commit previously written data to
stable storage. However, Commit RPCs do not write data from the
client to the server. As such, if the dirty bit on the page has
been set by a mmap'd write to an address in the page, it should
not be cleared. Clearing it causes the mmap'd write to by lost.
This patch fixes the problem by changing the 2nd argument to
vfs_busy_pages() to 0 for this case.
I doubt this bug has affected many, since it was inherited from
the old NFS client and was in 4.3 FreeBSD twenty years ago.
Although fspacectl(2) is FreeBSD 14 specific, a write(2) would
cause the same failure.

Using done_namei instead of ni_startdir did not
fix the crashes reported in the PR. Upon looking
more closely at the code, the only case where the
code near the end of nfsvno_open() needs to be
executed is when nfsvno_namei() has succeeded,
but a subsequent error was detected.
This patch uses done_namei to indicate this case.
Also, nfsvno_relpathbuf() should only be called for
this case and not whenever nfsvno_open() is called
with nd_repstat != 0. A bug was introduced here when
the HASBUF flag was deleted.

Its purpose is to reserve all I/O space belonging to physical memory
from nexus, preventing it from being handed out by bus_alloc_resource()
to callers such as xenpv_alloc_physmem(), which looks for the first
available free range it can get. This mimics the existing pseudo-driver
on x86.

The architecture nexus should handle allocation and release of memory and
interrupts. This is to ensure that system-wide resources such as these
are available to all devices, not just children of ofwbus0.
On powerpc this moves the ownership of these resources up one level,
from ofwbus0 to nexus0. Other architectures already have the required
logic in their nexus implementation, so this eliminates the duplication
of resources. An implementation of nexus_adjust_resource() is added for
arm, arm64, and riscv.
As noted by ian@ in the review, resource handling was the main bit of
logic distinguishing ofwbus from simplebus. With some attention to
detail, it should be possible to merge the two in the future.

Allow the nexus bus to own and manage interrupt resources. Currently,
interrupt resources on this architecture are managed completely by
ofwbus, but it is desirable that system-wide memory and interrupt
resources be managed by the top-level bus.
This is a pre-requisite to moving this resource management out of
ofwbus.

Merge commit '755d9301ca89f02956fd17858b9d4d821ab5c972' from the
vendor branch. This updates us from lua 5.4.2 to 5.4.4.
In addition, it switches around how we flavor liblua for the boot loader
and flua. This is done to reduce diffs with upstream and make it easier
to import new versions (the current method has too many conflicts to
resolve by hand): we include luaconf.local.h from luaconf.h (the only
change to this file is now that #include at the end). We then define
what we need to: for flua (which does very little) and one for stand
(which creates the new FLOAT type out of int64).

side of the first free, unallocated range. In iommu_gas_init_domain,
it is initialized to point to the node after the single free
range. Change it to point to the node before that free range, so that,
when 'lowaddr' is within the initial free range, the first allocation
search for free space below 'lowaddr' does not begin and end at an
address above 'lowaddr'. This fixes problems on a machine with Intel
