Rename 'show lockchain' to 'show locktree' and 'show threadchain' to 'show lockchain'.  The churn is because I'm about to add a new 'show sleepchain' similar to 'show lockchain' for sleep locks (lockmgr and sx) and 'show threadchain' was a bit ambiguous as both commands show a chain of thread dependencies, 'lockchain' is for non-sleepable locks (mtx and rw) and 'sleepchain' is for sleepable locks.
