Refactor fields in heap header to clean out information from dropped
features and also group related fields together more nicely.
Add fields to heap header for storing information about "huge" objects.

Refactor fractal heap IDs to include "flag byte" as part of the ID. This
byte will be used for the heap ID format version as well as flags to indicate
whether the heap object is a "tiny"/normal/"huge" object (with storage
mechanisms optimized for each type of object).

Fix the last scattered bunch of problems with the object deletion code,
which appears to be completely working now (for objects that are stored
within heap blocks - standalone objects aren't implemented yet).
Also, re-work the regression test to speed up some of the existing tests
and add in 100-200 more combinations of tests - overall, its probably even
slower than it was... :-/

Code checkpoint
Description:
Add in more new features for the fractal heap code, mostly bringing in
more ability for deleting objects (which isn't completely working yet).
Also, checkpoint free space manager code, which is essentially complete
(although it needs some more work after the metadata cache has some additional
features)

New feature & code cleanup
Description:
Update fractal heap to be able to insert objects into a direct block
hanging off the header.
