Merge import of OpenBSD source, ports and XF4 tree.

While here,
o clean up differences where possible
o whitespace cleanup
o ifdef ./. if defined()
o '...' ./. "..."
o echo foo > bar ./. echo foo >bar
o `...` ./. $(...) ./. $$(...)
o `...' ./. '...'
o modernize "our" tree, e.g. WWW in ports
o fix some typos and brainos introduced when renaming OpenBSD to MirBSD
o use hardware 80387 by default
o migrate Apache 1.3.28 OpenBSD ./. MirBSD ./. KAME
o work around as many CVS bugs as possible (add back/delete files, ...)

Import OpenBSD as of today again (seems pretty stable, I hope)

first part of mergeing OpenBSD and fixing whitespace and RCS IDs
untested script to build mirbsdksh on about every current GNU/Linux
the principle worked today at work. I'm pondering about config.h and
supported features, though; also, some more sections could be stripped.
Initial revision
these files were only to be added in vendor branch
these files don't belong into mirbsdksh, either
the last sync with OpenBSD seems to have introduced more manpage errors
we don't have alpha, and stuff like that belongs
into conf-end.h anyways (autoconf annoys)
