// Chrome implementation of FileSystemAccessPermissionContext. This class
// implements a permission model where permissions are shared across an entire
// origin.
//
// There are two orthogonal permission models at work in this class:
// 1. Active permissions are scoped to the lifetime of the handles that
//    reference the grants. When the last tab for an origin is closed, all
//    active permissions for that origin are revoked.
// 2. Persistent permissions, which are stored via ObjectPermissionContextBase,
//    allow for auto-granting permissions that the user had given access to
//    prior. Before user accepts the Extend Permission prompt, the permission
//    objects are simply "shadow grants" or "dormant grants", representing
//    recently granted permission, which are created together with active
//    permissions. After user accepts the Extend Permission prompt, dormant
//    grants become "extended grants", which can auto-grant permissions.
//
// All methods must be called on the UI thread.
