Setup an enumerator for listing matching objects on the modules.

This call will not block but will return an enumerator immediately.

`modules` : | The modules. [element-type Gck.Module]
`attrs` : | Attributes that the objects must have, or empty for all objects

`modules` : | The modules. [element-type Gck.Module]
`uri` : | The URI that the enumerator will match
`session_options` : | Options from GckSessionOptions
`error` : | A location to raise an error on failure.

Get a list of slots for across all of the modules.

`modules` : | The modules. [element-type Gck.Module]
`token_present` : | Whether to only list slots with token present
Returns : | A list of GckSlot objects, which should be freed with `gck_list_unref_free()`. [transfer full][element-type Gck.Slot]
