This adds the netstat command. All but one file is currently enabled.
That file does not currently build.
Also added libmemstat and libutil. libmemstat had a lot of code related
to kvm and kernel memory access disabled. This may or may not be an
issue.
The rtems shell commands should not exit but allow multiple
command attempts and some of the commands share code that
will exit. For this reason a common exit routine was
provided and code added to err.h to address this.
allow access to it.
This requires a full checkout of the FreeBSD 8.2 source code.
The checkout we have been using is missing at least the libc,
include, and sys directories. The script to copy files in is
crude.
This eventually needs to separate the manually written .h files
out and add the RTEMS specific network initialization support
with functionality to program the IP addresses and gateways as
the old stack did.
