Since the hal client is called in two places
(arch-wrs/wrs-calibration.c and time-wrs/wrs-time.c), put what is common
in the general include file provided by arch-wrs. Indeed this file
should be moved to arch-wrs/include (will be done in one of the
next commits).

This function is the only one I'm renaming at the moment, since
it's the only one that will change for sure (for wrs specific needs).

There is some more unix_something stuff, but I don't rename anything
else since it should remain the same as what is in arch-unix.

This commit is just a copy of arch-unix, as it is in commit 97c0c129

.
The only difference is in file names, as they have been renamed with
wrs- prefix

arch-wrs will host the stuff for WR switch architecture. It will
be very similar to arch-unix, with the only difference of using
wr switch HAL (Hardware Abstraction Layer) instead of the standard
unix "read/write/ioctl to dev" to drive the White Rabbit specific
hardware.

This patch-set creates the "time-" directory set, allowing different
time engines to be used for the unix architectures. This also
allows to cleanly create arch-wrs and time-wrs, done by Aurelio

This includes the time (and net) operations from arch-wrpc. Like bare,
arch-wrpc is not able to use a different timing engine than its own.

This commit separates to its own directory the timing code specific
to bere linux implementations.  If you build with ARCH=bare-i386
or ARCH=bare-i386-64, TIME=bare is automatically selected.

Please note how bare builds don't allow externally-set TIME=, as the
architecture Makefile forces "TIME := bare" (not "TIME ?= bare").

This is the first implementation of the concept ot "TIME=" on the
configuration of ppsi.  Time-related code that used to live in arch-unix
is now split into its own directory. If you have special timing hardware,
you can write your own pp_network_operations and pp_time_operations
in your own directory and select them using TIME= .

We'll do Linux-specific hardware timestamping soon, and WhiteRabbit as
well.

Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

The unix time and network operations are going to be used as a fall-back
solution by other timing engines.

For example, hardware-specific timestamping capabilities can be
selected (such as the Linux ioctl API) but if the Ethernet interface
(and thus the pp_instance) doesn't support the feature, related code
will be able to set back the unix operations in place.

The contents of this directory are pretty portable anyways, and
the internal files were actually called "posix-io.c" and so on.
So let's get rid of the too-politica "gnu-linux" naming and of
the too-little-political "posix" at the same time.  We build
on Unix roots, so let's call our architecture like that.

Since we have a call to bmc inside this function, we do not need to
unpack Announce message locally.

This patch fixes a bug with white rabbit extension, since it did not
update the foreign master record with most recent wrFlags. As a result,
at the end of wr handshaking, the slave (very often) did not handle
correctly the parentWrModeOn flag.

This fixes the correct behaviour of ppsi in arch-wrpc, where adjust_freq
is not available.
Still some more fixes may be needed in servo.c. I'm not sure about the
parameter -adj to be passed both in adjust_freq and adjust_offset case.
Anyway, this has been tested on two SPECs and reaches synchronization.

if the user passes "-DDIAG_PUTS=sth~ in USER_CFLAGS at build time, al
diagnostic messages are directed to this special puts (through sprintf
to a local buffer) instead of going to the normal printf (and thus the
default puts).

This is going to be used by wrpc-sw, to leave the default output channel
clean for the user shell.

Unfortunately, frame dumps cannot go to this special puts, as
lib/dump-funcs.c just call printf and I don't know how to fix that
without a massive change in the code.

Commit 7373cc02

 introduced a workaround for a suboptimal choice in
wrpc-sw about global variables (that were "common").  Commit 9ff25f86
of wrpc-sw fixed it, so this removes the workaround (which, btw,
prevents compilation of ppsi as a submodule of current wrpc-sw).
