Add new API's for object management:
virObjectPoolableDefGetDef
- Just return the obj->def from the object.
virObjectPoolableDefSetDef
- If the new @def is non-NULL, replace the previous obj->def with
the new @def argument calling the obj->defFreeFunc on the previous
obj->def. If the @def is NULL, then just clear the obj->def
leaving the caller to handle removal of the previous obj->def.
virObjectPoolableDefGetNewDef
- Just return the obj->newDef from the object.
virObjectPoolableDefSetNewDef
- If the new @newDef is non-NULL, replace the previous obj->newDef
with the new @newDef argument calling the obj->defFreeFunc on
the previous obj->newDef. If the @newDef is NULL, then just clear
the obj->newDef leaving the caller to handle removal of the
previous obj->newDef.
virObjectPoolableDefSwapNewDef
- Manage swapping the obj->newDef into obj->def by first calling
the obj->defFreeFunc on the current obj->def and then stealing
the obj->newDef into obj->def.
