misc: move ppp to a plugin
Type: refactor
Move PPP folder under vnet to the plugin folder, and modify some of path
of the #inlude<header> to the new path.
Add a plugin.c file to register a plugin.
Resolve ip4_input and ip6_input's dependency on PPP functions by moving
those calls to PPP's initialization.
Resolve osi's inter-plugin dependency on PPP by having it retrieve the
function pointer
Add ppp to the list of valid spelling words
