     * tsearch/config.h: Add some things convenient for testing.

     * tsearch/dwarf_tsearch.c: Convenient for some testing.

     * RUNTEST: the script had a couple of problems (typos). Fixed.

       Added comments about running the tests.

     * dwarf_tsearch.h: Provide a default DW_TSHASHTYPE

       for tsearchhash and use DW_TSHASHTYPE.

     * dwarf_tsearchbal.c,dwarf_tsearchbin.c,dwarf_tsearchepp.c,

       dwarf_tsearchred.c: Use DW_TSHASHTYPE.

     * dwarf_tsearchhash.c: use DW_TSHASHTYPE, add UNUSEDARG use.

       Now the primes list starts at 79, not 5 (the low numbers

       were really only for basic testing). Add UNUSEDARG

       though it is defined as empty here (it is for gcc

       to suppress some warnings).

     * tsearch_tester.c: Use DW_TSHASHTYPE.  Changed one

       error message to help match with input test files.

     * All .h, .c: Changed the return type of the hashfunc

       to be DW_TSHASHTYPE so it can easily be overridden.

       Unsigned long did not work well on a P64, IL32

       environment. Now it is easy to use -D to

       for folks in such an environment.

     * dwarf_tsearchbal.c: Deleted the unused little function rotatex().

     * dwarf_tsearchtester.c: Fixed compilation warnings (some of them).

     * dwarf_tsearchbal.c: Added a comment.
