This two files where just copied from ptp-noposix
script/Lindent was run on them.

ptpd_netif.h has not been removed from ptp-noposix, because hosted compilation
needs it.

After several back and forth, we agreed that softpll should live in
wrpc-sw, even if it is also used on the wr switch.  I don't pick up
the history, because the tool got renamed and moved several times.

This comes from commit 1e2c71d1f0e1094adc6c2eb46e30d4164262f85c, the
current master of ptp-noposix (the one that is currently a subproject)

The tool builds all releases travelling back from the current one up
to the named one. For example:

  ./tools/git-compileall master

  [... all the compiles ...]

   Number of failed builds: 0
   The log of all compiles is at /tmp/makeall.out.67Rf3n
   The md5sums of wrc.o are at /tmp/mdlog.sZXrAi

The tool was born for internal use, so it is misnamed and so on. But
it may be useful to others too.

Calibration uses a lot of internal variables, and it used to overflow
even a 3kB stack (by a little amount). This patch shares a temporary
buffer between two functions, so it takes 128 bytes less of stack, and
3kB fit for the wr-nic release.

The problem must still be studied, to reduce stack use.

This fixes a bug with negative hex numbers (that must
be printed as unsigned hex, without the minux sign).

The rule for "git submodule update" was wrong, so the command was
always performed.  This is a pain if you are using commits in the
submodule that are not yet committed in the supermodule. This always
happens during development.

I'm sorry for the inconvienence, and I thank Aurelio for noting this.

We are always pretty near to the end of RAM, so now that we
have a reserved stack area, we can also check if it overlows.
When it happens, let's print a message forever, so a user who
comes and see what's up will see it eventually.

Pretty often it happens that during trials we pick wrong external
functions (e.g., "printf") and the final link claims horribly about
dozens of undefined symbols.  By having an intermediate wrc.o we can
easily check which are the symbols we really leave undefined for libc
and libgcc to fill, before they resolve them by asking for something
else.

This renames ram.ld to ram.ld.S, adding a preprocessing rule. The
commit has no techcnical effect: it is only preparation for the next one.
