  1. Derive oldestActiveXid at correct time for Hot Standby.

  2. Start Hot Standby faster when initial snapshot is incomplete.

  3. Fix timing of Startup CLOG and MultiXact during Hot Standby

I was curious if anyone running into these problems has gotten a chance 
to test the 3 fixes committed here.  It sounded like Linas even had a 
repeatable test case?
