r8073: a successful rpc call from ejs!

the ejs_echo.c code is the stuff that needs to be auto-generated by
pidl. It only does echo_AddOne so far.

We also need a table for registering these calls. The code is
hard-wired for echo_AddOne for now.
(This used to be commit b1ea58ddc482c373783d16331dd07378010ba39a)
