New feature
Description:
Allow records in internal nodes to be removed, not just records in leaf
nodes.

Bug fix & new feature
Description:
Fix error in 3-node redistribution when nodes are only moving into the
middle node from the left & right nodes (which happens sometimes during
record removals).
Clean up internal insert & remove routines to remove lots of redundant
checking.
Added 3->2 node merge routine to handle more record removal cases.

FreeBSD 4.9 (sleipnir)

Bug fix & new feature
Description:
Fix a couple of off-by-one errors in assertions (code was actually correct)
for 3 node redistributions.
Remove "old" node removal code that is unused now.
Add more tests that verify that 2-node and 3-node redistributions are
working correctly for removals.

from leaves of level-1 B-trees.

New feature & code cleanup
Description:
Change some references from 'keys' to 'records', which is more correct for
this implementation.

only currently)
Added feature to perform preemptive 3->4 node splits (for leaves only
currently)

New feature & bug fixes
Description:
Checkpoint v2 B-tree code after getting preemptive 2->3 node splitting
working (for leaf nodes only at the moment, however).
Also, correct a problem with redistributing records that was probably
causing the failures on mir in yesterday's daily tests.
Ran code through purify on shanti and cleared up some warnings.
