Needed in the interim until we port the old model over
to the new interface. Long term we should have a cleaner
solution for controlling which models get compiled in.

list so we can choose to not include it in compile.

previous changeset.
SConscript:
Move System and PhysicalMemory sources from being full_system_sources
to base_sources, since they are now used in syscall emulation also.
Also add source files for PageTable and ProxyMemory objects.
Actual source files for PhysicalMemory and ProxyMemory are not committed
yet since they still need to be ported from old interface.

System object now exists for both fullsys and syscall emulation, as the
latter needs it so that Process objects can find the shared PhysicalMemory
for initialization.

Virtualize sinic
- The io registers are replicated many times in memory, allowing the NIC to
differentiate among several virtual interfaces.
- On the TX side, this allows multiple CPUs to initiate transmits at the same
time without locking in the software. If a partial packet is transmitted,
then the state machine blocks waiting for that virtual interface to complete
its packet. Then the state machine will move on to the next virtual
interface. The commands are kept in fifo order.
- On the RX side, multiple partial transmits can be simultaneously done.
Though a packet does not deallocate its fifo space until all preceeding
packets in the fifo are deallocated. To enable multiple receives, it
is necessary for each virtual nic to keep its own information about its
progress through the state machine.

Receive state must be virtualized since we allow the receipt of packets in
