wireproto: stop aliasing wire protocol types (API)

We generally shy away from aliasing module symbols. I think I
was keeping this around for API compatibility. We've already made
tons of other API breaks in the wire protocol code this release.
What's one more?

.. api::

   ``wireproto`` module no longer re-exports various types used to
   define responses to wire protocol commands. Access these types
   from the ``wireprototypes`` module.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
