This is a safe measure before adding UDP support, which adds a socket.
And we have other ongoing net-related activities too, so I'd better
spend 16 bytes now and feel safer.

I also change the prototype of the socket creation so the compile can
warn me where the locally-allocated socket must be changed.

The size saving is not huge, but this allows later creation of further
sockets with a smaller overhead (e.g.: the syslog socket that sends only
has no queue, and the snmp socket needs a very small buffer).

* library files can be built even if not used (this gets us more build-time
testing, as for example I usually build with no IP support).

* Some ifdefs are not needed, use HAS_IP instead. This adds a few
bytes to some configurations (not all, can't tell why), but I find it
acceptable.

This commit fixes all copyright notes, using "git blame" as a
reference.  For simple files I just added a 2-lines boilerplate about
being WR and GPL.

Some parts I left untouched:

  trivial-init and related files (unclear to me what this is,
  and pf-microcode.h is magic binary pfilter values).

  tools/lm32-etheruart: I don't know what this is and who the author is

  libsdbfs: this comes from another repo and I'd better not change it

  sfp_lib.h and hal_shmem.h: I lost track about the origin of this,
  among the several packages.

E.g. Kintex-7

I added -Wstrict-prototypes, that used to be included in -Wall settings
but is not.  Actually, I think it should be an error to not specify an
argument list by now.  If any, -traditional is there for old timers.

Fortunately no bug was exposed by the missing prototypes.

This has no effect on wrc.bin: board.h is renamed into board-wrc.h
and included by the new board.h. The new board-wrs.h is copied from
wr-switch-sw/rt/include/board.h

Update Etherbone config space with correct IP address.

wrc_main starts bootp whenever link goes up
Rever Arria2 sys clock to 125MHz -- we had packet loss at 62.5MHz
Added IP training support to the shell
Have the shell reset the packet filter when the MAC is changed
