This is needed to build sdb-lib for the target, in case you rely on
the default value for CROSS_COMPILE instead of using the environment
variable.

We don't want to call the real printf, which brings in the whole of
newlib, but it sometimes happen. So let's diagnose the problem
immediately rather than letting users wonder what is wrong with the
size.

Similarly, if building under ppsi, ensure we are not calling libgcc
division functions: any 64-bit division my be done with __div64_32
offered by ppsi/lib (copied from the kernel).

With this commit, when you select both the hardware and software uart,
ppsi diagnostics (controlled  by the "verbose" command) got to
the software uart, not to the hardware one. In this way you can run
the shell in a clean tty.

Unfortunately, frame dumps still reach the hardware uart, if frame
verbosity is greater than 1.

We need to link ppsi/proto-standard/libstd.a explicitly, but we also
need a rule to generate it, or parallel compilation fails saying it
has no rule. The makefile depended on build order (my fault), as
building ppsi/ppsi.o, with its rule), also built libstd.a

BTW, this removes ppsi/arch-wrpc/libarch.a from the dependencies,
because it is already linked in making ppsi/ppsi.o (otoh the need for
an explicit mention of libstd.a can't easily be solved in ppsi
itself, so it remains here).

In recent ppsi code, proto-ext-whiterabbit is not replicating
proto-standard any more, but rather it offers hooks for the additional
code it needs.  Thus, we need to link the library for standard PTP as
well, to pick some of the states for the WR state machine.

This source file is now part of ppsi itself, so it is removed from
wrpc-sw. The move helps improving cleaning up and maintaing ppsi
without committing to the supermodule each time something internal changes.

Split a rule into two rules, to make make happy.

In previous versions of make it was acceptable to list one or more
explicit targets followed by one or more pattern targets in the same
rule and it worked "as expected". However, this was not documented as
acceptable and if you listed any explicit targets AFTER the pattern
targets, the entire rule would be mis-parsed. This release removes
this ability completely: make will generate an error message if you
mix explicit and pattern targets in the same rule. You must split
these rules into two rules: one for the pattern and one for the
explicit targets. The Linux kernel source has already been modified in
this way (in newer kernels).

This is a copy of ptp-noposix/libposix/freestanding-wrapper.c, moved
into this project because it actually is only used here. The Makefile
now builds this one.

This move is needed in order to remove this faulty usleep and provide a
better one, while keeping the other fake functions called by ptp-noposix
code.

This command can return the .config file to the user. It can be useful
to trace what is actually running, as addition to the "ver"
command.  It is optional because it costs .5kB of binary size.

Example:

  wrc# config
    Current WRPC-SW configuration:
  CONFIG_RAMSIZE=90112
  # CONFIG_PTP_NOPOSIX is not set
  CONFIG_PPSI=y
  # CONFIG_CHECK_RESET is not set
  CONFIG_PPSI_VERBOSITY=0
  CONFIG_PPSI_RUNTIME_VERBOSITY=y
  CONFIG_STACKSIZE=2048
  CONFIG_PP_PRINTF=y
  # CONFIG_PRINTF_FULL is not set
  CONFIG_PRINTF_XINT=y
  # CONFIG_PRINTF_MINI is not set
  # CONFIG_PRINTF_NONE is not set
  CONFIG_PRINT_BUFSIZE=128
  CONFIG_ETHERBONE=y
  # CONFIG_DETERMINISTIC_BINARY is not set
  CONFIG_CMD_CONFIG=y

(This configuration amounts to a binary size of 86252 bytes, at this
commit).

This commit makes no effect, but it prepares for the following one.
In general, using an intermediate platform-agnostic linker script
when making wrc.o is not bad, so let's do it here.

The main reason why we need it is to force the "KEEP" command for the
".cmd" ELF section, introduced by the next commit.  The alternative to
this would be chaning the main linker script, which is worse in my
opinion.

If we add initcalls or similar stuff later, this bigobj.lds is the
place to do it.

New procedure that does not require PTP traffic, is much faster and doesn't kill the stack.
Requires recent endpoint version (wr-cores commit: 4713a98a).
Todo: modify locking functions in libptpnetif to automatically perform the calibration whenever
PTP enters slave mode.

The ppsi subproject now builds pp_printf by default, so the Makefile here
passes ~CONFIG_NO_PRINTF=y". Also, assign_TimeInternal() is not there
any more because it is just an assignment.

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.

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 adds copyright notes to all non-trivial source files,
unless they where already there (i.e. dev/endpoint.c alone).

I found authorship using the following script, run on commit "a2721762


documentation updated" (i.e, before automatic reindentation and other
trivial stuff by me):

  git grep -l . | grep -v sockitowm/ | \
  while read F; do
       echo "##### $F"
       git blame -w $F | \
         sed -e 's/^[^ ]* .//' -e 's/-[0-9][0-9]-[0-9][0-9] .*$//' | \
         sort | uniq -c | sort -rn
  done

Then I augmented each file with this boilerplate:

Then I removed all the lines that didn't apply. Sometimes I reordered
the authors to reflect who is the main author.
