Break out the broom for some cleanup work
Maintain the MAINTAINERS file. Removed src/plugins/*.am listings. Added a couple of plugins. Add vlib_process_create (vlib_main_t *vm, char *name, vlib_node_function_t *f, u32 log2_n_stack_bytes); /** @brief Create a vlib process * @param vm &vlib_global_main * @param f the process node function * @param log2_n_stack_bytes size of the process stack, defaults to 16K * @return newly-create node index * @warning call only on the main thread. Barrier sync required. */ This function makes it easy to spin up periodic processes when features are enabled for the first time. That coding pattern is highly recommended. Update the emacs-lisp plugin generator to use vlib_process_create, instead of generating static periodic process nodes.
