No point in calling a function just to dereference a pointer.

Thomas pointed out a namespace collision between the new timerlist
infrastructure I introduced and the existing timer_list.c

So to avoid confusion, I've renamed the timerlist infrastructure
to timerqueue.

The timerlist infrastructure is a thin layer over the rbtree
code that implements a simple list of timers sorted by an
expires value, and a getnext function that provides a pointer
to the earliest timer.

This infrastructure allows drivers and other kernel infrastructure
to easily implement timers without duplicating code.
