all VAX, PDP11: Add initial NAT based ethernet connectivity via SLiRP.

Browse Source 
This should work on all byte addressable host systems using GCC/clang to build.

The QEMU slirp code has been pried out of QEMU and stubs have been created to solve where the current slirp is entangled with the QEMU code.  Ths slirp/simh directory contains all the necessary include and glue files to make this useful.  Everything in the slirp directory is unmodified QEMU code.

#### Ethernet Transport Enhancements
* UDP packet transport. Direct simulator connections to HECnet can be
made without running a local packet bridge program.
* NAT packet transport. Simulators which only speak TCP/IP (No DECnet)
and want to communicate with their host systems and/or directly to
the Internet can use NAT packet transport. This also works for WiFi
connected host systems.
* Packet Transmission Throttling. When connected to a LAN which has
legacy network adapaters (DEQNA, DEUNA) on legacy systems, it is very
easy for a simulated system to overrun the receiving capacity of the
older systems. Throttling of simulated traffic delivered to the LAN
can be used to mitigate this problem.
* Reliable MAC address conflict detection.
