Make oldSnapshotControl a pointer to a volatile structure

Browse Source 
It was incorrectly declared as a volatile pointer to a non-volatile
structure.  Eliminate the OldSnapshotControl struct definition; it
is really not needed.  Pointed out by Tom Lane.

While at it, add OldSnapshotControlData to pgindent's list of
structures.
