56dc79cea0 IPC server: major fixes, test set for semaphores
- rewrite the semop(2) implementation so that it now conforms to the
  specification, including atomicity, support for blocking more than
  once, range checks, but also basic fairness support;
- fix permissions checking;
- fix missing time adjustments;
- fix off-by-one errors and other bugs;
- do not allocate dynamic memory for GETALL/SETALL;
- add test88, which properly tests the semaphore functionality.

e4e21ee1b2 Add MIB service, sysctl(2) support
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.

2d6bbeb0b9 Split minix distribution set
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.
