Webserver working for full website with LMP.

This version of code still does not work for UMP,
and also it does not work for httperf test.

Also, there is lot of commented out code which was helpful for me
in debugging the issue of randome page-fault.

Webserver working for small websites

Partially working version of the modified network stack.
Status: Networking works
Small website test works (Barrelfish website without pdfs)
Full website test does not work (Barrelfish website with pdfs)
Tests done with e1000n running on separate core

New tracing infrastructure

This is a Distributed Systems Lab project by
Alexander Grest <agrest@student.ethz.ch> and David Stolz <stolzda@ethz.ch>

newlib: build scc/arm/xscale

- mostly format changes
- some argument changes

Fixed the problem of netd crashing when ran from different core than driver.
The problem was non-initialized variables in contmng.c
Also, some cleanup is done in contmnt.c

Fixed the issues with nfs benchmarking code in net_throughput
Currently getting around 50MB/s speed for NFS read

Boots correctly for both freec and newlib

modified the webserver code to record the cache loading time.
also net_throughput now records the file loading time

Adding a new interface to support virtual nics
Also some boilerplate code is added there.
But still lot more code needs to be written before these
v_nics can be used.

Merge from ASPLOS tree.

Initial version of public stable barrelfish repository.
