This commit (temporarily) leaves MINIX 3 without a TCP/IP service.
Thanks go out to Philip Homburg for providing this TCP/IP stack in the
first place. It has served MINIX well for a long time.

Scripts for generating boot-to-ramdisk images are now available. These
can be used for example to boot from PXE or from a USB stick, as the
ramdisk are self-contained and do not rely on any block devices after
being loaded into RAM.
The image generation framework has also been slightly cleaned up in
order to better accomodate tarball sets bundling in images.

The new MIB service implements the sysctl(2) system call which, as
we adopt more NetBSD code, is an increasingly important part of the
operating system API. The system call is implemented in the new
service rather than as part of an existing service, because it will
eventually call into many other services in order to gather data,
similar to ProcFS. Since the sysctl(2) functionality is used even
by init(8), the MIB service is added to the boot image.
MIB stands for Management Information Base, and the MIB service
should be seen as a knowledge base of management information.
The MIB service implementation of the sysctl(2) interface is fairly
complete; it incorporates support for both static and dynamic nodes
and imitates many NetBSD-specific quirks expected by userland. The
patch also adds trace(1) support for the new system call, and adds
a new test, test87, which tests the fundamental operation of the
MIB service rather thoroughly.

The minix set is now divided into minix-base, minix-comp, minix-games,
minix-kernel, minix-man and minix-tests.
This allows massive space savings on the installlation CD because only
the base system used for installation is stored uncompressed. Also, it
makes the system more modular.

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.
