ipcpd: Use the term "layer" and deprecate "shim"

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.
