DHCP is working from netd now.
Also, all traffic is going to netd by default.

use of soft_filters from device_manager is partially written.
The device_manager connects with soft_filters service, shares memory with them.
The code compiles and patially works. The missing link is:
* When get_port call comes, it is not translated into filter_registration.
* When callback from register_filter comes, it is not translated into
return call informing success/failure of get_port call.
* A queue_manager_closure for every queue_manager is not yet created

First step in getting net_ports.if working.
This involves breaking the netd apart and implenting it as
net_device_manager library. The work is progressing in this direction,
but still quite a way from being complete.

This version just compiles with net_ports interface and net_device_manager
library, but it is not working yet.

Added net_queue_manager interface, and changed the code accordingly
in all drivers, ethersrv, lwip and applications.

Made read over nfs faster by parallelizing the chunk fetching. Also
now using more fair wait_for_condition which does not block
waiting on events like timer without handling pending incoming packets.

Also, added test for measuring nfs throughput in harness. And re-arranged
few files related to net_tests.
