PTP protocol defines two kind of sockets, "event" and "general". In spec, and
in raw socket as a general rule, this distinction is not present, but ppsi
makes use of both of them. So, with this patch, we use the same socket for
both. This solves a bug in the initialization of clockIdentity with the MAC
addr.
See proto-ext-whiterabbit/state-initializing.c, from line 36:

	id = DSDEF(ppi)->clockIdentity;
	mac = NP(ppi)->ch[PP_NP_GEN].addr;
	id[0] = mac[0];
	id[1] = mac[1];
	id[2] = mac[2];
	id[3] = 0xff;

some initializations are done in the main of wrpc-sw, so remove them
from state-initializing. With this patch, the ppsi standalone main will not
work, and must be upgraded as soon.

This patch is very important because wrpc-sw provides the ptp start/stop
commands in its shell. At each of them, sockets must be correctly created
and released, or NET_MAX_SOCKETS limit is easily reached

spec_calibrating_poll was using ep_get_deltas instead of
spec_read_calibration_data, like freestanding-wrapper.c does in wrpc-sw.
The whole spec-calibration.c is obsolete, since it should simply be a
wrapper for wrpc-sw functions defined in
ptp-noposix/libposix/freestanding-wrapper.c

Pre-Master and Passive state are not used in the current implementation
of WR protocol, so do not compile nor link them, in order to save space

define VERB_LOG_MSGS if you want very verbose msg when log verbosity=2.
As default, they are not even compiled, in order to save space in the final
binary executable.

When ppsi is used as a module for wr-pc, Master/Slave selection is no more
defined at compile time, but selected by 'mode' shell cmd. The obsolete
WRMODE is hence relevant only when ppsi-bin main is compiled.

This patch is to substitute the obsolete spec-socket.c implementation by
calling the functions provided by wrpc-sw api (called ptpd_netif.h).

Actually, it is not clear why ptpdexp_sync_state_t and wr_servo_state_t
exist both. This was inherited from wrpc/ptp-noposix.

Removed any dependency from ppsi's internal copy of spec drivers, and the
drivers' source itself.

With this patch, now we ppsi is fully compatible with wrpc-sw drivers.

In order to compile ppsi main (which, in the future, will become obsolete)
you can now either:
- copy ppsi project inside the wrpc-sw dir (or, better, use the ppsi as
wrpc-sw submodule)
- go into arch-spec/Makefile and modify the WRPCSW_ROOT var
