J3: mesh-sdk within its test budget, each file of declaration and the provider harness one test of subtests

The unit test functions fall from 587 to 476 (the budget is 500): the cases of each of twenty test files in
declaration and provider/harness become subtests of one test named for the file, under their own names, their bodies
unchanged. Integration tests stay at 30 (budget 50).
