Andy Green f9f6bb66fe lws_validity: unified connection validity tracking 
Refactor everything around ping / pong handling in ws and h2, so there
is instead a protocol-independent validity lws_sul tracking how long it
has been since the last exchange that confirms the operation of the
network connection in both directions.

Clean out periodic role callback and replace the last two role users
with discrete lws_sul for each pt.
