srcu: Debloat the <linux/rcu_segcblist.h> header
Linus noticed that the <linux/rcu_segcblist.h> has huge inline functions which should not be inline at all. As a first step in cleaning this up, move them all to kernel/rcu/ and only keep an absolute minimum of data type defines in the header: before: -rw-r--r-- 1 mingo mingo 22284 May 2 10:25 include/linux/rcu_segcblist.h after: -rw-r--r-- 1 mingo mingo 3180 May 2 10:22 include/linux/rcu_segcblist.h More can be done, such as uninlining the large functions, which inlining is unjustified even if it's an RCU internal matter.
