This change rewrites much of the glue code in testing/fuzz.go to work more analogously to T.Run. This results in improved behavior: * If a fuzz target returns without calling F.Skip, F.Fail, or F.Fuzz, 'go test' will report an error and exit non-zero. * Functions registered with F.Cleanup are called. * The user can re-run individual inputs using -run=FuzzTarget/name where name is the base name of the seed corpus file. We now print the 'go test' command after a crash. This change doesn't correctly handle T.Parallel calls yet, but it should be easier to do that in the future. Highlighted parts of this change: * Instead of creating one F for all targets, create an F for each target. F (actually common) holds the status, output, and cleanup function list for each target, so it's important to keep them separate. * Run each target in its own goroutine via fRunner. fRunner is analogous to tRunner. It runs cleanups and catches inappropriate Goexits and panics. * Run each input in its own goroutine via T.Run. This enables subtest filtering with -test.run and ensures functions registered with T.Cleanup (not F.Cleanup) are run at the appropriate time.
