Some NICs added padding to the Ethernet II frames causing bad frame
lengths and GPB unpack fails. This adds a 2-byte length field to the
DIX frame to circumvent this.

This adds an IPC Process that uses DIX Ethernet with an Ethertype that
is configurable at bootstrap. This allows parallel DIX layers over the
same Ethernet network with different Ethertypes (and one LLC
layer). It allows jumbo frames in the future, and should avoid the
problems we have with some routers not handling LLC traffic very
well. The destination endpoint ID is sent as a 16 bit integer, so the
maximum payload is 1498 bytes in standard Ethernet, and 8998 bytes
when Jumbo frames are used.
The implementation is very similar to the Ethernet LLC IPCP, so it is
implemented using preprocessor macros in the single source instead of
duplicating code.

The rbuff uses the PTHREAD_COND_CLOCK for its condition variables, but
the flow_read was passing a time it got from the CLOCK_REALTIME_COARSE
clock. This causes the blocking reads not to timeout correctly.
The oping was updated to detect server timeouts and finish gracefully.

This changes the terminology to use layer instead of DIF and deprecate
the word "shim" for the IPCPs that attach to Ethernet LLC and UDP .The
terminology has not yet been changed in the variable names etc.
This reflects the design choices in Ouroboros to make IPCPs pure
resource allocators instead of also providing an "IPC service". The
Ouroboros IPCPs that attach to Ethernet and UDP implement the
allocator and are thus not really shims.
