The alignment for the pSeries NVDIMM does not depend on runtime
constraints. This means that it can be done in device parse
time, instead of runtime, allowing the domain XML to reflect
what the auto-alignment would do when the domain starts.
This brings consistency between the NVDIMM size reported by the
domain XML and what the guest sees, without impacting existing
guests that are using an unaligned size - they'll work as usual,
but the domain XML will be updated with the actual size of the
NVDIMM.

Right now, the logic that takes care of deciding whether expensive
tests should be run or not is not working correctly: more
specifically, it's not possible to use something like
$ VIR_TEST_EXPENSIVE=1 ninja test
to override the default choice, because in meson.build we always
pass an explicit value that overrides whatever is present in the
environment.
We could implement logic to make this work properly, but that
would require some refactoring of our test infrastructure and is
arguably of little value given that running
$ meson build -Dexpensive_tests=enabled
is very fast, so let's just stop telling users about the variable
instead and call it a day.

In [1], changes were made to remove the existing auto-alignment
for pSeries NVDIMM devices. That design promotes strange situations
where the NVDIMM size reported in the domain XML is different
from what QEMU is actually using. We removed the auto-alignment
and relied on standard size validation.
However, this goes against Libvirt design philosophy of not
tampering with existing guest behavior, as pointed out by Daniel
in [2]. Since we can't know for sure whether there are guests that
are relying on the auto-alignment feature to work, the changes
made in [1] are a direct violation of this rule.
This patch reverts [1] entirely, re-enabling auto-alignment for
pSeries NVDIMM as it was before. Changes will be made to ease
the limitations of this design without hurting existing
guests.

just hides it due to the buffering done by FILE *. Mixing UNIX FD I/O

Currently, slot 1 is only allowed to be used by the LPC device.
Relax this requirement and allow to use slot 1 if it was explicitly
specified by the user for any other device type. In this case the LPC
device will have the next available address.
If slot 1 was not used by the user, it'll be reserved for the LPC
device, even if it is not configured to make address assignment
consistent in case the LPC device becomes necessary (e.g. the user
adds a console or a video device which require LPC).

Support modeling of the 'isa' controller for bhyve. User can manually
define any PCI slot for the 'isa' controller, including PCI slot 1,

When domain configuration requires the 'isa' controller to be present,
automatically add it on domain post-parse stage.
Now, as this controller is always available when needed, it's not
necessary to implicitly add it to the bhyve command line, so remove
bhyveBuildLPCArgStr().
Also, make bhyveDomainDefNeedsISAController() static as it's no longer
used outside of bhyve_domain.c.
As more than one ISA controller is not supported by bhyve,
and multiple controllers with the same index are forbidden,
so forbid ISA controllers with non-zero index for bhyve.
