Towards 64-bit pageids. bufferManager can handle 64-bit offsets, but recordid.page is still 32 bit...

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.

Preliminary version of logical logging linear hash. (No latching yet, and there are some bugs re-opening a closed hash.)

Implemented indirect pages, and fixed some bugs here and there. (Still need to add transactional support for indirect pages...)

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.

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