This is going to extend virDomainLoader enum. The reason is that
once loader path is NULL its type makes no sense. However, since
value of zero corresponds to VIR_DOMAIN_LOADER_TYPE_ROM the
following XML would be produced:
<os>
<loader type='rom'/>
...
</os>
To solve this, introduce VIR_DOMAIN_LOADER_TYPE_NONE which would
correspond to value of zero and then use post parse callback to
set the default loader type to 'rom' if needed.
