[libvirt] [PATCH 12/19] storage: Introduce virStoragePoolObj{Get|Set}Autostart

[John Ferlan]

Rather than have the logic in the storage driver, move it to virstorageobj.

NB: virStoragePoolObjGetAutostart can take liberties with not needing the
same if...else construct.  Also pass a NULL for testStoragePoolSetAutostart
to avoid the autostartLink setup using the autostartDir for the test driver.
