Historically the argv -> xml convertor wanted the same default machine
as we'd set when parsing xml. The latter has now changed, however, to
use a default defined by libvirt. The former needs fixing to again
honour the default QEMU machine.
This exposed a bug in handling for the aarch64 target, as QEMU does not
define any default machine. Thus we should not having been accepting
argv without a -machine provided.

The virQEMUCapsGetDefaultMachine() method doesn't get QEMU's default
machine any more, instead it gets the historical default that libvirt
prefers for each arch. Rename it, so that the old name can be used for
getting QEMU's default.

We don't honour the QEMU default machine type anymore, always using the
libvirt chosen default instead. The QEMU argv parser, however, will need
to know the exacty QEMU default, so we must record that info.

QEMU is probed through monitor fd to check capabilities during libvirtd init.
The monitor fd is closed after probing by virQEMUCapsInitQMPCommandFree
that calls virQEMUCapsInitQMPCommandAbort that calls qemuMonitorClose,
the latter one notifies the event loop via an interrupt handle in
qemuMonitorUnregister and after then closes monitor fd.
There could be a case when interrupt is sent after eventLoop is unlocked
but before virEventPollRunOnce blocks in poll, shortly before file
descriptor is closed by qemuMonitorClose. Then poll receives closed monitor
fd in fdset and returns EBADF.
EBADF is not mentioned as a valid errno on macOS poll man-page but such
behaviour can appear release-to-release, according to cpython:
https://github.com/python/cpython/blob/master/Modules/selectmodule.c#L1161
The change also fixes the issue in qemucapabilitiestest. It returns
Bad file descriptor message 25 times without the fix.

Generation of the ACL API policy is a "automated process"
based on this perl script which "worked" with the changes to
add nwfilter binding API's because they had the "nwfilter"
prefix; however, the generated output name was incorrect
based on the remote protocol algorithm which expected to
generate names such as 'nwfilter-binding.action' instead
of 'nwfilter.binding-action'.
This effectively changes src/access/org.libvirt.api.policy entries:
org.libvirt.api.nwfilter.binding-create ==>
org.libvirt.api.nwfilter-binding.create
org.libvirt.api.nwfilter.binding-delete ==>
