srcu: Automatically determine size-transition strategy at boot



This commit adds a srcutree.convert_to_big option of zero that causes
SRCU to decide at boot whether to wait for contention (small systems) or
immediately expand to large (large systems).  A new srcutree.big_cpu_lim
(defaulting to 128) defines how many CPUs constitute a large system.
