Subject: list: introduce list_next_entry() and list_prev_entry()
Add 2 trivial helpers list_next_entry() and list_prev_entry(), they can
have a lot of users including list.h itself. In fact the 1st one is
already defined in events/core.c and bnx2x_sp.c, so the patch simply moves
the definition to list.h.
