07b35f4e20 scattered, and poorly tested fixes. finer grained latching for tree nodes; throttle c0-c1 merge when c0 is small; fix delta computations for c0 throttling; disable short pauses for c1-c2 merge. this gets the bulk load throughput up to 8500, but workloada is still slow

dc75f6d1f0 Implemented snowshoveling, with caveats. 
This commit includes concurrency control for datapages, the new backpressure for the c0-c1 merger, and (untested) support for defining NO_SNOWSHOVEL, and using the old approach.

There are a number of important limitations:
 - statistics gathering is somewhat messed up
 - the c0-c1 merge thread polls for new data
 - on a sequential write, if the writers stall, the merge thread could empty memory and initiate an unnecessary merge.  Instead, we should never finish a merge if c0 is less than N% full
 - this commit introduces yet another batch of nasty mutex contention issues

eb8b57378a laying the groundwork for snowshoveling; as of this commit, pointers and null padding happens in an order that should let us query incomplete tree components. We should only need short page latches at this point (so that we do not look at partially written keys/values)
