This CL mainly changes: a) moving the interface in struct provider_vtab to std::function; b) code cleanup, such as moving the declaration closer to the uses, using explicit type conversion. Test: recovery_component_test Test: minadbd_test Test: Sideload a package on marlin. Change-Id: Id0e3c70f1ada54a4cd985b54c84438c23ed4687e
