make: git commit template

Add a commit template for tagging of commits
with a type. Later tooling can then process
the commit log and generate reports of new features
etc.

Usage:

The template is automatically added to the current repository
by make install-dep.
(git config commit.template .git_commit_template.txt)

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 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.

tap: crash in multi-thread environment

In tap tx routine, virtio_interface_tx_inline, there used to be an
interface spinlock to ensure packets are processed in an orderly fashion
  clib_spinlock_lock_if_init (&vif->lockp);

When virtio code was introduced in 19.04, that line is changed to
  clib_spinlock_lock_if_init (&vring->lockp);
to accommodate multi-queues.

Unfortunately, althrough the spinlock exists in the vring, it was never
initialized for tap, only for virtio. As a result, many nasty things can
happen when running tap interface in multi-thread environment. Crash is
inevitable.

The fix is to initialize vring->lockp for tap and remove vif->lockp as it
is not used anymore.
