So far all the properties we are trying to fetch are device
properties, i.e. -device $dev on qemu command line. Change
misleading variable names to express what's queried for better.

QEMU translates the cache mode of a disk internally into 3 flags.
'write-cache' is a flag of the frontend while others are flag of the
backing storage. Add capability which will allow expressing it via the
frontend attribute.

On Core i5 650 x86_64 kvm guest fail to start with error [1] for next cpu config:
<cpu mode='host-model' check='partial'>
<model fallback='allow'/>
<feature policy='require' name='x2apic'/>
</cpu>
The problem is in full CPU calculation in virQEMUCapsInitHostCPUModel.
It is supposed to include features emulated by qemu and missed on host. Some of
such features may be not included however.
For Core i5 650 host CPU is detected as Westmere and reported CPU as
SandyBridge. x2apic is missed on host and provided by installed qemu. The
feature is not mentioned in reported CPU features explicitly because SandyBridge
model include it. As a result full CPU does not include x2apic too.
Solution is to expand guest cpu features before updating fullCPU features.
[1] error: the CPU is incompatible with host CPU: \
Host CPU does not provide required features: x2apic

So far we are repeating the following lines over and over:
if (!(virSomeObjectClass = virClassNew(virClassForObject(),
"virSomeObject",
sizeof(virSomeObject),
virSomeObjectDispose)))
return -1;
While this works, it is impossible to do some checking. Firstly,
the class name (the 2nd argument) doesn't match the name in the
code in all cases (the 3rd argument). Secondly, the current style
is needlessly verbose. This commit turns example into following:
if (!(VIR_CLASS_NEW(virSomeObject,
virClassForObject)))
return -1;

Whenever we declare a new object the first member of the struct
has to be virObject (or any other member of that family). Now, up
until now we did not care about the name of the struct member.
But lets unify it so that we can do some checks at compile time
later.
The unified name is 'parent'.
