Paolo Bonzini fb8a9677b1 rcu: do not mention atomic_mb_read/set in documentation

Dr. David Alan Gilbert 5626f8c6d4 rcu: Add automatically released rcu_read_lock variants 
RCU_READ_LOCK_GUARD() takes the rcu_read_lock and then uses glib's
g_auto infrastructure (and thus whatever the compiler's hooks are) to
release it on all exits of the block.

WITH_RCU_READ_LOCK_GUARD() is similar but is used as a wrapper for the
lock, i.e.:

   WITH_RCU_READ_LOCK_GUARD() {
       stuff under lock
   }

Note the 'unused' attribute is needed to work around clang bug:

Paolo Bonzini ac06724a71 docs: create config/, devel/ and spin/ subdirectories 
Developer documentation should be its own manual.  As a start, move all
developer-oriented files to a separate directory.

Also move non-text files to their own directories: docs/config/ for
QEMU -readconfig input, and docs/spin/ for formal models to be used
with the SPIN model checker.
