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.
