Another 1.5% -- this is the basics of the istable patch I posted a few

times, but without the compile-time generated table.  I still plan to
do the compile-time generated table.  I decided not to do it in ap_ since
the table was really tied into functions in util.c.

find_token() completely rewritten so that it doesn't chew up memory.  Take
out some dead code as well.
