Subject: 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.
