26// This class manages the WebIntents table within the SQLite database passed
27// to the constructor. It expects the following schema:
28//
29// web_intents
30//    service_url       URL for service invocation.
31//    action            Name of action provided by the service.
32//    type              MIME type of data accepted by the service.
33//    title             Title for the service page
34//    disposition       Either 'window' or 'inline' disposition.
35//
36// Web Intent Services are uniquely identified by the <service_url,action,type>
37// tuple.
38//
39// Also manages the defaults table:
40//
41// web_intents_defaults
42//    action            Intent action for this default.
43//    type              Intent type for this default.
44//    url_prefix        URL prefix for which the default is invoked.
45//    user_date         Epoch time when the user made this default.
46//    suppression       Set if the default is (temporarily) suppressed.
47//    service_url       The URL of a service in the web_intents table.
48//    extension_url     The URL for an extension handling intents.
49//
50// The defaults are scoped by action, then type, then url prefix.
