Merge branches branch-3.7.2 and stat3-enhancement into a new branch for
testing purposes.
Get stat3 working after import from trunk-based the stat3-enhancement branch.
There is still a problem in the wal2 test.
Merge the branch-3.7.2 changes into the stat3-3.7.2 subbranch.  Also fix
some test script issues.
Veryquick and min.rc tests now passing.
