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.

- Fixed missing variable interpolation because of single quotes
- Replaced /bin/sh in gen_uEnv.txt.sh with /usr/bin/env bash as the default
echo doesn't support '-n'
- Fixed some whitespace errors
- A succesful build requires for now to skip the gold linker on OSX.

tests many complex system/process memory interaction cases.
has to run as root so it can flush the FS cache; needed to
force FS cache misses for unmapped pages.
See the comment in test74.c for a full description of what the tested
cases are.
also re-enable filemap on arm
We currently have a few of the POSIX tests failing because filemmap
is enabled by default. The working assumption is that these program
pass a pointer to the file server that points to a not yet loaded
data segment. When the file server tries to access that data it
therefore generates a pagefault and a call to itself it can not
handle because it is unable to first return the current call.

Put the boot arguments in uEnv.txt and not in cmdline.txt to allow
a more dynamic configuration of the system. We now also pass the
u-boot board_name parameter to the kernel.
Keep kernel and modules in the first 256MB of memory in preparation
for the beaglebone. That target only has 256 MB of memory.
