Re: Removing "long int"-related limit on hash table sizes

I'm not particularly on board with s/long/int64/g as a universal
solution.  I think that most of these usages are concerned with
memory sizes and would be better off as "size_t".  We might need
int64 in places where we're concerned with sums of memory usage
across processes, or where the value needs to be allowed to be
negative.  So it'll take case-by-case analysis to do it right.

BTW, one aspect of this that I'm unsure how to tackle is the
common usage of "L" constants; in particular, "work_mem * 1024L"
is a really common idiom that we'll need to get rid of.  Not sure
that grep will be a useful aid for finding those.
