Subject: Repair performance problem in SI segment manipulations: iterating
 through MAXBACKENDS array entries used to be fine when MAXBACKENDS = 64. It's
 not so cool with MAXBACKENDS = 1024 (or more!), especially not in a
 frequently-used routine like SIDelExpiredDataEntries.  Repair by making
 procState array size be the soft MaxBackends limit rather than the hard
 limit, and by converting SIGetProcStateLimit() to a macro.
