serializing/deserializing Flags in function\nparameters, add an enum class TestFlags and Flags to some\nfunction parameters, both for input and output and Signals.\n\nWhile at it, update the ipa_interface_test.\n\nSigned-off-by: Paul Elder \nReviewed-by: Laurent Pinchart \n\n---\nNo change in v5\n\nChanges in v4:\n- make flags also passed directly (as opposed to const references)\n- remove [TEST] from commit subject\n\nChanges in v3:\n- s/TestFlags/TestFlag/\n- add [scopedEnum] to enum Testflag\n\nChanges in v2:\n- use new attribute-based mojom definition for Flags\n---\n
