9ec77eef2d qemuxml2argvtest: Test expected error messages
When an error is expected, the error message will be checked.
This is expressed by creating an additional ".err" file containing
the expected error message.

It is added in order to make sure the expected errors
are not masked by other errors during test execution while
leveraging the existing framework.

In order to keep it simple, an input file cannot be reused
anymore to cover several expected error cases configured
in the test code. An input file can still be reused by creating
a test case specific symlink.

For consistency, the mock needs to report an error now, too,
as every failure must have an error; otherwise a test case will
fail.

Require LC_ALL=C explicitly to make sure error messages are not
localized for testing.

d3f3c2c97f domain_conf.c: auto-align pSeries NVDIMM in virDomainMemoryDefPostParse()
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.

cf81c85bf5 tests: Don't advertise VIR_TEST_EXPENSIVE to users
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.

63af8fdeb2 qemu: revert latest pSeries NVDIMM design changes
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.

This reverts the following commits:

- commit 2d93cbdea9
  Revert "formatdomain.html.in: mention pSeries NVDIMM 'align down' mechanic"

- commit 0ee56369c8
  qemu_domain.c: change qemuDomainMemoryDeviceAlignSize() return type

946c815024 tests: don't mix FILE* and UNIX FD I/O on same stream
There is currently a hang in test27 that exhibits itself on FreeBSD 11.4
only. The behaviour is that virCommandProcessIO gets POLLIN on the
FD for stdout, but read() blocks. Meanwhile commandtest also blocks
in write for stderr because the pipe buffers are full.

This fix in commandhelper likely does not really address the root cause
just hides it due to the buffering done by FILE *. Mixing UNIX FD I/O
and FILE * I/O is bad practice regardless.

4277e61e22 bhyve: soften requirements for slot 1
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).

16a2882350 bhyve: support 'isa' controller for LPC
Support modeling of the 'isa' controller for bhyve. User can manually
define any PCI slot for the 'isa' controller, including PCI slot 1,
but other devices are not allowed to use this address.

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.

f8ec7c842d rpc: use new virt-ssh-helper binary for remote tunnelling
This wires up support for using the new virt-ssh-helper binary with the ssh,
libssh and libssh2 protocols.

The new binary will be used preferentially if it is available in $PATH,
otherwise we fall back to traditional netcat.

The "proxy" URI parameter can be used to force use of netcat e.g.

  qemu+ssh://host/system?proxy=netcat

or the disable fallback e.g.

  qemu+ssh://host/system?proxy=native

With use of virt-ssh-helper, we can now support remote session URIs

  qemu+ssh://host/session

and this will only use virt-ssh-helper, with no fallback. This also lets
the libvirtd process be auto-started, and connect directly to the
modular daemons, avoiding use of virtproxyd back-compat tunnelling.

019b13dd20 rpc: merge logic for generating remote SSH shell script
Three parts of the code all build up the same SSH shell script
snippet for remote tunneling the RPC protocol, but in slightly
different ways. Combine them all into one helper method in the
virNetClient code, since this logic doesn't really belong in
the virNetSocket code.

Note that the this change means the shell snippet is passed to
the SSH binary as a single arg, instead of three separate args,
but this is functionally identical, as the three separate args
were combined into one already when passed to the remote system.
