added bulk-insert APIs, prevent c1-c2 from outrunning c0-c1 by too much, and fix the overshoot computations in merge manager (roughly corresponds to run 20)

fix a deadlock (double setting thread_fd = -1 in race at startup), lazily spawn new worker threads. This will save some ram, and will lead to shorter server thread listings in gdb

add new server implementation that uses FILE to buffer I/O, and handles a smaller, fixed number of connections -- leads to an almost 4x speedup on no-ops on nehalem

Reopening existing trees now seems to work (no thorough tests yet). Added some network opcodes for statistics and debugging (not all are implemented yet). Reduce verbosity of server and client library.

Implemented network iterator protocol. It hasn't been tested or hooked up to anything because logstore iterators don't exist yet.

Reworked memory allocation and network protocol. This gargantuan commit also reduces the default size of C0, and removes quite a bit of redundant logic and error handling.
...
The tests now pass, except that check_merge never terminates (it takes too long) and check_mergelarge still is not passing.
For better luck running this version of the code, turn off stasis' concurrent buffer manager. We're doing something bad that leads to deadlocks with the concurrent buffer
manager. Another (the same?) bug less-frequently leads to page corruption with the old stasis buffer manager.
