These changes have no effect at this point, but are the initial steps
introducing host builds. Some changes are minor cleanups, some depend
on CONFIG_HOST_PROCESS which is not defined at this point.

Also, this changes how to mac address is retrieved in patching pfilter
rules. I'd better use format_mac(get_mac) for the verbose message,
so get_mac is also the source for patching the rules.

register and get_mac/set_mac are guaranteed to be in-sync.

This removes TRACE_DEV(), turning it into pll_verbose() and wrc_verbose().

The functions are enabled and disabled by kconfig, with defaults matching
the previous behaviour.

So nothing changes, but the binary is smaller because the previous
wrc_debug_printf() was silent because of a run-time conditional
(though hardwired false at build time). The condional is now at build
time.  We save around 2k, between strings and calling code, in
all wrc builds (nothing is saved in wrs, which is verbose by default,
nor in devel_build_test_defconfig where all verbose options are on)).

devel_build_test_defconfig: enable all verbose options

The misleading TRACE thing was only used in wrs builds, and expanded
to pp_printf.

Considering we don't want to remove messages from the softpll in wrpc,
this commit turns trace onto pp_printf.

include/trace.h is different in wr-switch. This uses an ugly ifdef
to make wr-switch rt_cpu code build here unmodified.

The variable was used to mask a few diagnostic messages but was always
set to 1. Since such messages are actually few at this time, remove
the variable altogether.

The code, however, included a hardwired check for servo messages, used
by the ptp-noposix callers.  This commit preserves the behaviour while
removing the dependency from ptp-noposix headers.  The result is ugly
but temporary, because we are going to phase out ptp-noposix.
