1) Write zserv api commands( one of each type ) to the side. This will allow us to use them as input for a fuzzer. 2) Add -c <file to pass to zapi read process> into zebra as a run-time option of we've turned on fuzzing. While in and of itself these are not terribly useful( you still need an external fuzzer ), they provide an infrastructure to allow tools like afl to test the zapi.
