moved spawn flags into spawndomain.h

Added local loopback device

net_latency now uses core info from SKB
Relying on core information from SKB is the way to go. Until now we just
used cores 0 through 15, but that is only correct for sbrinz1.

net_latency benchmark now relies on spawn_wait_core()
This allows us to wait for the benchmark runs to terminate, and removes
the hack of using sleep.

Added support for memory affinity and dry runs in ethernet latency benchmark
The dry runs are just normal runs whose result is thrown out.

Extended latency benchmarks to actually do something useful
The ethernet latency benchmark now does a statically configured number
of runs and then calculates some values on the result. Also net_latency
now runs the benchmark on each core for a start. But since spawn_exit
seems to be broken somehow on other cores than 0, we just sleep a bit
and then spawn the next one. :-/

net_latency benchmark suite started
At the moment its pretty much just proof of concept, to see how well
multiple runs of the ethernet latency benchmark work. Looks good for
now.
