[FEATURE: #148

] userspace/tools/wrs_ext_pps_latency: Support aligning the PPS out to PPS input in GM

1. Add new paramter CONFIG_EXT_PPS_LATENCY_PS in dot-config.
   Calibration is needed to align the PPS out to PPS input in GM mode.
2. Add new variable ext_pps_latency_ps in struct spll_stats, using it
   to transfer the ext_pps_latency parameter to WRPC-SW.
3. Change SPLL_STATS_VER to 4, modify the related function.
4. (deleted from the commit)
   Add a new tool function: wrs_ext_pps_latency, which will change
   the Main PLL phase shift in GM mode, according to the parameter
   CONFIG_EXT_PPS_LATENCY_PS in dot-config. Add this new function to
   startup-mb.sh, making it autostart.

- update wrsSpllStatusGroup to recognize ver=3
- update wrsSpllStatusGroup and wrsSpllVersionGroup to
  properly complain to syslog when not recognizing version

Updates:
- information in the body of the message about severity was
  not aligned with the severity reported to syslog, now all
  is aligned
- aligned format of all messages from snmpd that use snmp_log()

Now wr_date depends on libwr.

Rename fields in the struct wrsSpllVersionGroup_s to reflect SNMP objects'
names.

Add "Build by" of spll

Use softpll_export.h instead of softpll_ng.h to handle stats exports from
the softpll.

For details, please check the following commit in the wrpc-sw repo
softpll: move stats defines to new file softpll_export.h

Additionally two new align state values:
ALIGN_STATE_WAIT_CLKIN
ALIGN_STATE_WAIT_PLOCK

It was possible that SNMP objects in expert branch don't update.
It pop-up in following scenario:
1. slave switch is started with no ntp configured
2. read via snmp from slave
3. master switch is started with no ntp configured
4. slave sync to master and set it's time, by this system clock on slave is set
   to earlier date
5. read via snmp from slave will end up in the same results in expert branch of
   the MIB.

Our part of SNMP implementation used "time" function for calculating SNMP's
cache timeouts. When clock is set backwards then cache can be valid for very
long time.

Monotonic clock is used instead from ulit.c (libwr)

Add util.c to the compilation.

Add following spll version info:
--wrsSpllVersion
--wrsSpllBuildDate

Additionally:
--update Makefile
--update MIB
--update init.c
--increase version number of spll_stat structure due to new fields
--support version 2 of spll_stat structure in wrsSpllStatusGroup

Please note that this commit requires changes done in wrpc-sw commit:
revision: report build information via spll_stats structure
