* Ported libtelnet.a and telnetd from FreeBSD.
* The subdirectory is called "libtelnet" instead of "telnet" (as usual), since telnetd
expects some headers to be found in libtelnet/ (which I could have changed as well,
just in case you very much prefer telnet/).
* I needed to disable some stuff to make it compile, and it's absolutely not tested,
so it might as well not work yet.
