bufferMananger is (really!) re-entrant now, performed big refactoring to prevent deadlocks, check_transactional2 ran overnight without coring, w/ 25 threads, and 10000 allocate/write/reads per thread. (The whole test suite was run in a loop...)

bufferMananger is *really* reentrant now! (I think) However, the same thread may not load a page more than once. So, LLADD has to be altered so that it never calls loadPage() more than once per operation (more efficient), and/or pin/unpin need to be implemented. An easy way to do pin/unpin is to have them pull things out of the cache replacement list, and then re-insert them.

Continuing work on multi-threading. r/w access to buffer manager getting close, but still buggy.

Cleaning up bufferManager / page for locking. Want to limit access to the Page struct.

page.c is re-entrant (mostly), and now reuses DeRalloced space properly. (For now, BufferManager still is not re-entrant, and also prevents space from being reused.)

Log truncation. (But no checkpoints, so it doesn't get called... it does pass testing though. :)

Logwriter can now handler partial log entries correctly (it ignores them)
...
Buffer Mananger no longer steals pages pre-maturely
Alloc is an operation, and correct.
Caching broken out into a new module
Wrote a utility to translate a log file into human-readable ascii.
