Improve density of the B-tree further. For greater depths of B-trees,
the gains are over 100%...
Also, don't split internal nodes with 3->4 splits, use a 1->2 split
instead, so that the density of the nodes around a split is maximized.
Tested:
Mac OS X/PPC 10.4 (amazon)
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)

Split edge nodes in the tree with a 1->2 node split, instead of a 2->3 node
split, which creates a more dense tree when a pattern of record insertions
occurs (because it leaves behind full nodes instead of 2/3 full nodes).
Tested:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Linux/32 2.4 (heping)
Solaris/64 2.9 (shanti)

Revert passing the v2 B-tree class to callbacks, it turns out to be
unnecessary. Also revert have a "class private" pointer for each v2 B-tree
class.
Add in support for the different flavors of fractal heap 'huge' objects
also.
Tested on:
FreeBSD/32 4.11 (sleipnir)
Linux/64 2.4 (mir)
Solaris/64 2.9 (shanti)

Update code formatting a little and refactor to add a better mechanism
for performing callbacks when removing records from the B-tree or deleting
entire B-tree.
Testing:
FreeBSD 4.11 (sleipnir)
Linux/64 2.4 (mir)
Linux/32 2.4 (heping)
Mac OS 10.4 (amazon)

Interim checkin of code changes moving management of the is_dirty flag
into the cache code.
Description:
Prior to this checkin, management of the is_dirty flag was handled
above the level of the metadata cache. This can no longer be allowed,
as it introduces a race condition in the proposed fix for a cache
coherency bug in PHDF5.
Solution:
Move management fo the is_dirty flag to the cache code proper.
Entries are now marked as dirty via a flag on the unprotect call.
Platforms tested:
