Add an initial autotools setup.

The main iperf binary is compiled, along with a static libiperf, the unit
tests, and a profiled iperf binary.

The tests, and the profiled iperf binary do not get installed.

To compile, run:

./bootstrap.sh
./configure
make

It has all the normal make options (they come mostly for free). e.g.:

You can run "make install" to install it.
You can run "make dist" which will create a distribution tarball.
You can run "make check" to run all the tests.

I backed up the existing Makefile as "src/Makefile.old" in case folks want to
use that still.
