prog_hash_table: Convert to using util/hash_table.h.
Improves glretrace -b servo.trace (a trace of Mozilla's servo rendering
engine booting, rendering a page, and exiting) from 1.8s to 1.1s. It uses
a large uniform array of structs, making a huge number of separate program
resources, and the fixed-size hash table was killing it. Given how many
times we've improved performance by swapping the hash table to
util/hash_table.h, just do it once and for all.
This just rebases the old hash table API on top of util/, for minimal
diff. Cleaning things up is left for later, particularly because I want
to fix up the new hash table API a little bit.
v2: Add UNUSED to the now-unused parameter.
