rcu: Update stall-warning documentation Add documentation of CONFIG_RCU_CPU_STALL_VERBOSE, CONFIG_RCU_CPU_STALL_INFO, and RCU_STALL_DELAY_DELTA. Describe multiple stall-warning messages from a single stall, and the timing of the subsequent messages. Add headings. Remove RCU_SECONDS_TILL_STALL_RECHECK because this value is now computed at runtime from RCU_CPU_STALL_TIMEOUT, so that sysfs changes to the timeout value now directly affect the RCU_SECONDS_TILL_STALL_RECHECK value.
