It is now possible to register page types before Tinit() is called, so that they may be used by recovery.

Sears Russell
362b1036de
Changed CLR log format so that it is identical to update entries. The old format pointed back to an earlier
...
entry in the log, complicating truncation significantly. The new format copies log entries into their CLRs,
and is somewhat redundant, as redo and undo information is stored in the CLR, but the undo information will
never be used...

New "default" buffer manager that aims to replace the current one, but

c2fa9913b1
Added partial implementation of range tracking for pinning arbitrary
...
regions. Currently, tracks regions, and is O(m log(n)) for each
operation, where m is the number of transition points per range, and n
is the number of transition points in the system. A transition point is
a place in memory where the pincount changes.
