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

Minor cleanup, added ability to calculate the global average number of
buckets traversed per find(). Added a warning for code that actually
relies upon PBL's way of interpreting insert.

Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier
of pages, so it doesn't suggest ones that aren't already in the buffer pool unless it has to.

Completely new blob implementation. Slower than the old one was supposed to be, but is correct, and extremeley
simple. It simply writes the pre-image and post-image of each blob to the log using TpageSet.

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.
