fix minor stats bugs; pull most stats computation into update_progress. The idea is that update_progress and tick, which are easily amortized, are the only stats things that need to grab latches

amortize the computation of statistics (but not mutex acuqisitions) across many tuple insertions. Also, refactor stats stuff with latch contention in mind (but it still grabs too many latches...). This commit causes check_tcpclient to emit warnings on my machine. Not sure if it will happen on production hardware

restore support for concurrent disk reads; logserver was accidentally using a findTuple function that assumed diffs. This commit uses rwlc, and requires Stasis -r1393 or better

admission control *almost* works; c1 sometimes blocks for a long time when a new c2 is created

admission control is now behaving properly (but there are still no concurrent writes, or bounds on how long admission control throttles a given writer)

Rewrite merge thread synchronization code, update status messages, implement preliminary (and ineffective) admission control, and force write merged data every megabyte (so that prograess can be tracked by admission control. Also, refactor quite a few things.
