libiberty already has hashtab.c.  It seems confusing to have both
hashtab.c and hashtable.c.  The difference between them seems to be
that hashtab.c is generic, while hashtable.c is specialized to only
work on strings, and to omit deleting entries from the hash table.

If we are going to move hashtable.c to libiberty, perhaps we could
give it a different name, like hashstr.c or something like that.
