73b64e4d2e Initial code for incremental checkpoint in WAL mode. This check-in compiles 
on unix and runs as long as you do not engage WAL mode.  WAL mode crashes and
burns.  Consider this check-in a baseline implementation for getting the new
capability up and running.

286a288493 Add a new xShmBarrier method to the VFS - a shared-memory fence operation. 
Implement the same in both unix and win32.  Use it to make the WAL subsystem
more robust.
