Add regression tests scripts for multi-IP FIBs exercising the send,
receive and forward path tagging packets with both the ifconfig fib
option or using ipfw, running ICMP6, TCP/v6 and UDP/v6 tests and
testing both setfib(2) as well as the SO_SETFIB socket option.

At 16 FIBs a total of over 64k return codes/replies/stati are checked,
sometimes multiple times (in different ways, e.g. the reflected request
as well as ipfw counter values).

The scripts need two or three machines to run and are thus not added
to the tools/regression framework but only to tools/test.

Add a TestFloat based test suite for floating-point implementations
currently supporting sparc64. After a `make depend all` there are
three programs; testsoftfloat for testing against the SoftFloat in
src/lib/libc/softfloat for reference purposes, testemufloat for
testing the emulator source in src/lib/libc/sparc64/fpu and testfloat
for testing with the installed libc. Support for other architectures
can be added as needed.

Add the DTrace test makefile for the test suite distributed in OpenSolaris.

Add $FreeBSD$.
Describe the other two directories in here.

Fix a couple of typos.

malloc.c A program to benchmark and test malloc.

README reads:
This directory is for test programs.

A test program is one that will excercise a particular bit of the system
and try to break it and/or measuring performance on it.

Please make a subdir per program, and add a brief description to this file.
