[PATCH v2 6/8] util: Add virObjectPoolableHashElementGet*Key

[John Ferlan <jferlan@xxxxxxxxxx>]

Add a pair of accessor API's:

   virObjectPoolableHashElementGetPrimaryKey
   virObjectPoolableHashElementGetSecondaryKey

which will return the requested key from the object to the caller.

It is up to the caller to check the returned key and error if the
return value is NULL.
