kmemtrace, rcu: fix linux/rcutree.h and linux/rcuclassic.h dependencies

Browse source 
Impact: build fix for all non-x86 architectures

We want to remove percpu.h from rcuclassic.h/rcutree.h (for upcoming
kmemtrace changes) but that would break the DECLARE_PER_CPU based
declarations in these files.

Move the quiescent counter management functions to their respective
RCU implementation .c files - they were slightly above the inlining
limit anyway.
