The status XML parser function virDomainObjParseXML could not pass in
parseOpaque into the post parse callbacks. Add a callback which will
allow hypervisor drivers to fill it from the 'virDomainObj' data.

When parsing status XML the post-parse callbacks can't access any
private data present in the status XML as the private bits were parsed
after invoking post-parse callbacks.
Move the invocation so that everything is parsed first.

Move the check for boot elements into a separate function
and remove its dependency on the parser-supplied bootHash table.
Reconstructing the hash table from the domain definition
effectively duplicates the check for duplicate boot order
values, also present in virDomainDeviceBootParseXML.
Now it will also be run on domains created by other means than XML
parsing, since it will be run even for code paths that did not supply
the bootHash table before.

Further patches will introduce validation and a default setting
of def->os.bootDevs in postParse.
Introduce a feature flag to opt out of this and set it in the vmx
driver, otherwise we would be adding it <boot dev='hd'/> into every
vmx config despite having no way to change it.

Trying to set any cache for <disk device='lun'/> makes no sense.
Such disk translates into -device scsi-block on the command line
and the device lacks any cache setting because it's merely a
middle man between qemu and real SCSI device.

The domain capabilities XML contains host CPU model tailored to a
specific hypervisor and since it's enclosed in <mode name='host-model'>
element rather then the required <cpu> it's impossible to directly use
the host CPU model as an input to, e.g., cpu-compare command. To make
this more convenient, vshExtractCPUDefXML now accepts full domain
capabilities XML and automatically transforms the host CPU models into
the form accepted by libvirt APIs.

Both cpu-compare and cpu-baseline commands accept more that just CPU
definition XML(s). For users' convenience they are able to extract the
CPU definition(s) even from domain XML or capabilities XML. The main
differences between the two commands is in the number of CPU definitions
they expect: cpu-compare wants only one CPU definition while
cpu-baseline expects one or more CPUs.
The extracted code forms a new vshExtractCPUDefXML function.
