[PATCH v2 05/15] conf: Introduce allocator for virDomainIOThreadIDDef

[Michal Privoznik]

So far, iothread configuration structure (virDomainIOThreadIDDef)
is allocated by plain g_new0(). This is perfectly okay because
all members of the struct default to value 0 anyway. But soon
this is going to change. Therefore, replace those g_new0() with a
function so that the default value can be set consistently in one
place.
