successfully run linux netscape 2.0b3 with a QMAGIC ld.so and libc/libm
that I found on some linux machine that I _think_ is running slackware 3.0.
There are still problems.. ld.so claims the libraries are the wrong
format, but it still runs anyway.. :-/ The QMAGIC ld.so also screams
about needing ld.so.cache, and running a linux ldconfig is quite
educational. You soon learn to run "chroot /compat/linux /bin/ldconfig"
where ldconfig is living in /compat/linux/bin. :-]
(Lets just say that it puts loads of symlinks in /usr/lib otherwise :-)
Changed vnodep -> vp for consistency with the rest of the kernel, and
changed iparams -> imgp for brevity.
kern_exec.c:
Explicitly initialized some additional parts of the image_params struct
to avoid bzeroing it. Rewrote the set-id code to reduce the number of
logical tests. The rewrite exposed a mostly benign bug in the algorithm:
traced set-id images would get ktracing disabled even if the set-id didn't
happen for other reasons.

1. stepping over syscalls (gdb ni) sends you to DDB, and returned
to the wrong address afterwards, with or without DDB. patch in
i386/i386/trap.c below.
2. the linux emulator (modload'ed) still causes panics with DIAGNOSTIC,
re-applied a patch posted to one of the lists...
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).
Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.
Kernel must be compiled with "options COMPAT_LINUX" for this to work.
