Add a helper to quickly determine if a hostdev is a PCI device,
instead of doing a tedious 'if' check with hostdev mode and
subsys type.

We're going to add logic to handle the case where a previously
existing PCI device does not longer exist in the host.
The logic was copied from virPCIDeviceNew(), which verifies if a
PCI device exists in the host, returning NULL and throwing an
error if it doesn't. The NULL is used for other errors as well
(product/vendor id read errors, dev id overflow), meaning that we
can't re-use virPCIDeviceNew() for the purpose of detecting
if the device exists.

libxlNodeDeviceDetachFlags() and qemuNodeDeviceDetachFlags() are mostly
equal, aside from how the virHostdevmanager pointer is retrieved and
the PCI stub driver used.
Now that the PCI stub driver verification is done early in both functions,
we can use the virDomainDriverNodeDeviceDetachFlags() helper to reduce
code duplication between them. 'driverName' is checked inside the helper
to set the appropriate stub driver.
The helper is named with the 'Flags' suffix, even when the helper itself
isn't receiving the flags from the callers, to be compliant with the
ACL function virNodeDeviceDetachFlagsEnsureACL() that is being called
inside it and was called from the original functions. Renaming the helper
would implicate in renaming REMOTE_PROC_NODE_DEVICE_DETACH_FLAGS, and all the
related structs inside remote_protocol.x, to be compliant with the ACL
rules.
This is not being checked at this moment, but we'll fix check-aclrules.py to
verify all the helpers that calls ACL functions in domain_driver.c shortly.

virStringListAdd hides the fact that a O(n) count of elements is

The use case VIR_ALLOC_VAR deals with is very unlikely. We had just 2
legitimate uses, which were reimplemented locally using g_malloc0 and
sizeof instead as they used a static number of members of the trailing

Remove VIR_ALLOC_VAR since in most cases the direct implementation is
shorter and clearer and there are no users of it currently.

During testing of my patch v6.10.0-rc1~221 it was found that
'ovs-vsctl get Interface $name name' or
'ovs-vsctl find Interface options:vhost-server-path=$path'
may return a string in double quotes, e.g. "vhost-user1". Later
investigation of openvswitch code showed, that early versions
(like 1.3.0) have somewhat restrictive set of safe characters
(isalpha() || '_' || '-' || '.'), which is then refined with
increasing version. For instance, version 2.11.4 has: isalnum()
|| '_' || '-' || '.'. If the string that ovs-vsctl wants to
output contains any other character it is escaped. You want to be
looking at ovsdb_atom_to_string() which handles outputting of a
single string and calls string_needs_quotes() and possibly
json_serialize_string() in openvswitch code base.
Since the interfaces are usually named "vhost-userN" we are
facing a problem where with one version we get the name in double
quotes and with another we get plain name without funny business.
Because of json involved I thought, let's make ovs-vsctl output
into JSON format and then use our JSON parser, but guess what -
ovs-vsctl ignores --format=json. But with a little help of
g_strdup_printf() it can be turned into JSON.
