The CD now boots directly from the ISO 9660 filesystem instead of using
MBR partitioning with Minix file systems. This saves some space on the
CD and reduces memory requirements by some unknown amount as the root
ramdisk is completely eliminated.
The x86 hard drive image creation is also rewritten in the same
fashion.
The setup is modified to be more NetBSD-like (unpacking sets
tarballs instead of blindly copying the CD contents). Splitting MINIX
into sets is done in another commit due to it being a nightmare to
rebase.
Since MINIX lacks union mounts for now, a bunch of ramdisks are
generated at run-time to make parts of the filesystem writeable for the
CD. This solution isn't ideal, but it's enough for an installation CD.

This patch adds support for the wait4 system call, and with that the
wait3 call as well. The implementation is absolutely minimal: only
user and system times of the exited child are returned (with all other
rusage fields left zero), and there is no support for tracers. Still,
this should cover the main use cases of wait4.

- assert() is macro which is defined as empty, while panic is always
present. I added an explicit abort() after the macro to make sure the
function never returns in case of wrong flags.
- Fixed gcc build with -NDEBUG, -Os for ARM.
* A few 'may be used uninitialized' messages
* A few new missing support library functions where added in libminc.

. get rid of includes in libcompat_minix:
. move configfile.h to minix/include/
. all others are unneeded as they point to other files
. merge the .c files with libc
