* examples/ecc-benchmark.c (bench_dup_hh): Rename, and use
ecc->dup pointer.
(bench_dup_jj): ... old name.
(bench_add_hh): Rename, and use ecc->addd_hh pointer.
(bench_add_jja): ... old name.
(bench_dup_eh, bench_add_eh): Deleted.
(bench_curve): Update, and delete curve25519 special case.
(main): Update table headers accordingly.
