Alexander Korotkov ff1975ddd0 pg_controldata: Fix possible errors on corrupted pg_control 
Protect against malformed timestamps.  Also protect against negative WalSegSz
as it triggers division by zero:

((0x100000000UL) / (WalSegSz)) can turn into zero in

XLogFileName(xlogfilename, ControlFile->checkPointCopy.ThisTimeLineID,
             segno, WalSegSz);

because if WalSegSz is -1 then by arithmetic rules in C we get
0x100000000UL / 0xFFFFFFFFFFFFFFFFUL == 0.
