MEM: Add port proxies instead of non-structural ports

Browse source 
Port proxies are used to replace non-structural ports, and thus enable
all ports in the system to correspond to a structural entity. This has
the advantage of accessing memory through the normal memory subsystem
and thus allowing any constellation of distributed memories, address
maps, etc. Most accesses are done through the "system port" that is
used for loading binaries, debugging etc. For the entities that belong
to the CPU, e.g. threads and thread contexts, they wrap the CPU data
port in a port proxy.

The following replacements are made:
FunctionalPort      > PortProxy
TranslatingPort     > SETranslatingPortProxy
VirtualPort         > FSTranslatingPortProxy

* TranslatingPortProxy Object Declaration for SE.
*
* Port proxies are used when non structural entities need access to
* the memory system. Proxy objects replace the previous
* FunctionalPort, TranslatingPort and VirtualPort objects, which
* provided the same functionality as the proxies, but were instances
* of ports not corresponding to real structural ports of the
* simulated system. Via the port proxies all the accesses go through
* an actual port and thus are transparent to a potentially
* distributed memory and automatically adhere to the memory map of
* the system.
