Pushed with very minor adjustments --- mainly, that I rewrote the commit
message to emphasize the change in postgres.bki conventions, since that
could possibly bite someone in more-surprising ways than simple removal
of a function.

I went ahead and removed everything in bootscanner.l and bootparse.y
that could be removed without provoking a compile error. I was slightly
astonished at how many there were. One gets the impression that there
was once a good deal of very low-level code in the bootstrap grammar.
I didn't try very hard to trace the commit history, but I did note that
almost all of the removed #includes dated to 1996 or so. I'm surprised
they survived Bruce's occasional attempts at removing unused #includes;
maybe his script didn't check .y/.l files.
