Some random code cleanups, and implemented a naive lock manager. (Still need to tie it into LLADD...)

Refactored bufferMananger / pageCache, so that bufferMananger handles loading an unloading pages, and pageCache only implements the replacement policy.
...
Also, used memprof to detect and remove all memory leaks (at least all memory leaks that are encountered by check_transactional2), and fixed a number of misuses of the pblHash.

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.
