6afe26749a Enable building with MKDEBUG and MKDEBUGLIB
The way these options work is by creating files that contain debugging
symbols and stashing them in a dedicated set. The minix-debug set has
been created for this purpose, but it will probably have to be refined
since it has been tested only with the default options with an i386
cross-build.

LSC: Amended to support many combination of MKDEBUG, MKDEBUGLIB, with
     and without X11, for both intel and arm.

d991a2bea3 Retire sysuname(2), synchronize sys/utsname.h
Now that uname(3) uses sysctl(2), we no longer need sysuname(2).
Backward compatibility is retained for old statically linked
binaries for a short while.

Also remove the now-obsolete MINIX3-specific "arch" field from the
utsname structure.  While this is an ABI break at the libc level,
it should pose no problems in practice, because:

- statically linked programs (i.e., all of the base system) are not
  affected, as they will use headers synchronized with libc;
- the structure is getting smaller, thus, older dynamically linked
  programs (typically in pkgsrc) using the new libc will end up with
  garbage in the "arch" field, but it is unlikely they will use this
  field anyway, since it was specific to MINIX3;
- new dynamically linked programs using an old libc could end up with
  memory corruption, but this is not a scenario that is expected to
  occur in the first place - certainly not with programs from pkgsrc.

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.

29346ab043 PM: add support for wait4(2)
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.

594df55e53 Abstract away minix_kerninfo access
Instead of importing an external _minix_kerninfo variable, any code
using the shared kernel page should now call get_minix_kerninfo(3).
Since this is the only logical name for such a function, rename the
previous get_minix_kerninfo call to ipc_minix_kerninfo.

1facb0487c libc: add posix_spawn family of functions
The implementation is taken from newlib (BSD licensed) and test84 is based

1dcfbcd173 Remove support for call profiling
The entire infrastructure relied on an ACK feature, and as such, it
has been broken for years now, with no easy way to repair it.
