Subject: [PATCH 03/62] Let MokManager follow a MokTimeout var for timeout
length for the prompt
This timeout can have the values [-1,0..0x7fff]; where -1 means "no timeout",
with MokManager going directly to the menu, and is capped to 0x7fff to avoid
unecessary long timeouts. The default remains 10, which will be used whenever
the MokTimeout variable isn't set.
