The following implements expanding chained hash tables for strings and
numbers. This is unmodified from a special-purpose program (having to
do with reading a large number of files with name=id pairs and doing
various operations on them). Chain lengths are not monitored; instead,
the table is invariably expanded whenever it becomes 2/3 full. Entries
may be neither removed nor modified.

An essentially-unrelated function called `string' maintains a string
pool such that string(x) == string(y) iff strcmp(x,y)==0 (the program
typically stores each name several times, and often needs to test for
name equality, so this helps there).
