By the time we reach exit in parent, child already exited or execed.
We should not re-run libc cleanup code.
While at it, introduce bb_daemon_helper() and add a few comments.

Those two spaces after tab have no effect, and always a nuisance when editing.

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

Added O_RDONLY where improves readability. Note: O_RDONLY == 0,
so it is there even if not specified.

- Rewrite kbd_mode and setconsole
- Introduce and use console_make_active() and xopen_xwrite_close()
- honour buffer-reservation method as set by the user (dumpkmap, loadkmap)
- shrink rtcwake and some console-tools
Saves about 270 Bytes

standard one even has different syntax!
std: "openvt -c 12", we: "openvt 12"
std: "openvt top", we: complain that "top" is not a number.
openvt: implement -c -w -s (-l -f -v are also accepted but ingnored)

TODO_config_nommu documents what I managed to compile so far
(yay! msh works! cool). inetd, telnetd, httpd still do not compile. TODO
Also make fork(), daemon() produce warnings on compile stage
(in addition to erros on link stage).

no preceding prototype

(will close all fd's > 2 on daemonization now)
getty: fix "getty -" support, and also do not try to chown/chmod "-"
telnetd: fix "lost ctty" bug
Yet another attempt on saner function names:
bb_sanitize_server_stdio(0/1) -> bb_sanitize_stdio() + bb_daemonize();

things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes... General cleanup pass. What I've
been doing for the last couple days.
And it conflicts! I've removed httpd.c from this checkin due to somebody else
touching that file. It builds for me. I have to catch a bus. (Now you know
why I'm looking forward to Mercurial.)
