Add a mechanism to escape infinite AML While() loops.
Add a loop counter to force exit from AML While loops if the count
becomes too large. This can occur in poorly written AML when the
hardware does not respond within a while loop and the loop does not
implement a timeout. The maximum loop count is configurable. A new
exception code is returned when a loop is broken, AE_AML_INFINITE_LOOP.
