Fixed broken min_rec_lsn() semantics; before, if there were not outstanding transactions / writes,

then these calls would return flushedLSN(). The problem was that flushedLSN wasn't guaranteed to
return a pointed to the beginning of a log entry.

All tests that pass with LOG_TO_FILE now pass with LOG_TO_MEMORY, but LOG_TO_MEMORY is slow, and seems to be

killing malloc's performance for some reason. (linearHashNTA spends many seconds in free() between unit
tests...)

The logger now calls fwrite half as often as it used to. This could be improved significantly, but some latching details internal to the logger need to be worked out first.

Rewrote / refactored page.h. Now, it uses a freelist to reclaim slotid's within a page, and is implemented as two seperate modules. The first handles lsn's, and (will soon) check the type of each page, and then delegate work to a particular implementation of the second module.

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!) 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.
