Move scanint8() to numutils.c

Browse Source 
Move scanint8() to numutils.c and rename to pg_strtoint64().  We
already have a "16" and "32" version of that, and the code inside the
functions was aligned, so this move makes all three versions
consistent.  The API is also changed to no longer provide the errorOK
case.  Users that need the error checking can use strtoi64().
