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

more bugfixes / cleanup. latching is probably overly conservative at this point, but ycsb bulkload finally seems to work

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.

Refactoring of logtable. Cleaned a bunch of includes, and logtable is now a template. This is in preparation for the new merge policy

create memTreeComponent class. Moved memTreeIterator, rbtree_t and tearDownTree into it (still need to move changableMemTreeIterator into it...)
