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:
