When the I/O thread quits (e.g. due to an I/O error, lseek()
error, whatever), any subsequent virFDStream API should return
error too. Moreover, when invoking stream event callback, we must
set the VIR_STREAM_EVENT_ERROR flag so that the callback knows
something bad happened.

This is only used in qemu_command.c, so move it, and clarify that
it's really about identifying if the serial config is a platform
device or not.

Some qemu arch/machine types have built in platform devices that
are always implicitly available. For platform serial devices, the
current code assumes that only old style -serial config can be
used for these devices.
Apparently though since -chardev was introduced, we can use -chardev
in these cases, like this:
-chardev pty,id=foo
-serial chardev:foo
Since -chardev enables all sorts of modern features, use this method
for platform devices.

ISA specifically isn't a valid config for arm/aarch64, but we've

vcpu properties gathered from query-hotpluggable cpus need to be passed
back to qemu. As qemu did not use the node-id property until now and
libvirt forgot to pass it back properly (it was parsed but not passed
around) we did not honor this.
This patch adds node-id to the structures where it was missing and
passes it around as necessary.
The test data was generated with a VM with following config:
<numa>
<cell id='0' cpus='0,2,4,6' memory='512000' unit='KiB'/>
<cell id='1' cpus='1,3,5,7' memory='512000' unit='KiB'/>

Introduces support for virDomainSetMemory. This also serves an an

complicated method, this time including an EPR and embedded param.
This commit adds support for virDomainSendKey. It also serves as an
example of how to use the new method invocation APIs with a single
"simple" type parameter.
Update the generator to generate basic property type information for
each CIM object representation. Right now, it generates arrays of
hypervCimType structs:
struct _hypervCimType {
const char *name;
const char *type;
bool isArray;
};
This commit introduces functionality for creating and working with
invoke parameters. This commit does not include any code for serializing
and actually performing the method invocations; it merely defines the
functions and API for using invocation parameters in driver code.
HYPERV_DEFAULT_PARAM_COUNT was chosen because almost no method
invocations have more than 4 parameters.
Functions added:
* hypervInitInvokeParamsList
* hypervFreeInvokeParams
* hypervAddSimpleParam
* hypervAddEprParam
* hypervCreateEmbeddedParam
* hypervSetEmbeddedProperty
* hypervAddEmbeddedParam
* hypervFreeEmbeddedParam

When one has a non-blocking stream and aborts or finishes it without
removing the callback, any event loop invocation will trigger that
callback, but it cannot be removed any more. We cannot remove the
callback automatically from virStream{Abort,Finish} functions due to

because it is not easy to find out the reason for.
