Log Message:
Pull up following revision(s) (requested by riastradh in ticket #1798):

        tests/lib/libc/string/t_swab.c: revision 1.3
        lib/libc/string/swab.c: revision 1.20

swab(3): Rewrite this to be understandable.

And make the tests work, and exercise all lengths up to 100.
Evidently the previous definition, presumably tightly optimized for
1980s-era compilers and CPUs, was too hard to understand, because it
was incorrectly tested for two decades and broken for years.
