Moved Ieee154Address and LqiRead to radio folders.

As mentioned in the todo of
http://docs.tinyos.net/tinywiki/index.php/BLIP_2.0_Platform_Support_Guide
I moved some radio specific code to the specific radio folders.
ReadLqi now in radio chips folder.

Rather than use a bunch of #defines that defeat the purpose of the
modularity of TinyOS I moved the appropriate Lqi code to the relevant
radio folder.
Created a simple interface for Blip.

Rather than wiring directly to the CC2420 driver, this interface layer
allows Blip to wire to something more generic.
Improved routing table printing.

Now full 128 bit IP addresses print correctly.
Added number column and fixed width
Routing table printing is now well formatted.
Adding support for stateless autoconfig to blip

Currently a work in progress. Not sure if it compiles and I haven't
tested it.
More progress in implementing SLAAC
changes for the rpi
Split Ieee154BareC into two files

The metadata interfaces that BLIP needs are now their own configuration
file, in case a radio driver wants to provide Ieee154BareC without
providing any of the metadata features (such as LPL or a PacketLink
layer). These should be logically separated anyway.
removing all the old DS2411 code
Cleaned up the DS2411 code for Epic

- Changed variable and macro names. Removed anything refering to Dallas
as that doesn't make much sense anymore.
- Moved onewire to the system folder and made a more intuitive Hpl file
in epic/chips
- Moved LocalIeeeEui64 code to its own folder in platforms/epic. This
should be separated from the ds2411 chip.
- Made the filenames and file functions easier to understand. It is
still 7 files to get the Eui64, but that is better than 11 and they make
more sense and are located in intuitive folders.
Removed LED from DHCP code

An errant file was still using LEDs. Not good for running on battery
power.
