This picks a new ppsi, which is needed for several reasons. We have
been using it for a while now, so it's a safe upgrade.  Being ppsi a
Kconfig thing itself, we now need to make wrs_defconfig first.

Also, the new ppsi.h defines INST which is pre-defined by net-snmp, so
include ieee1588_types.h alone, as we only need ClockIdentity by now.

On higher storm of traffic, in the time between scheduling the tasklet and
executing it, I was loosing cntrs overflow information already (was overwritten
by all-the-time-incrementing counters in HDL).

File provides information about pstats version, number of counters per word
stored in memory and number of counters per each port.

We don't need a ppsi_defconfig any more, as it is now the default.
Also, use a full defconfig, so it's explicit what the options are.

This fills the information by parsing the output of "wr_mon -g"
and "wr_mon -p".

Parsing is data-struct driven, and the strings must match the one
printed by wr_mon. If they don't a log message is generated:

   18:02:54 192 snmpd[1468]: wrs_ppsi_parse_line: can't find key "seource:"

To test, you can export WRS_SNMP_MON_FNAME and WRS_SNMP_MON_FNAME_P to
name two text files that can be opened instead of a pipe from wr_mon.

A problem with COUNTER64 remains, but it is a bug in netsnmp. See next
commit.

This is needed if for example it is called in a pipe that is then closed.

meanwhile, remove trailing white space.

Version items are now fake strings, as I still miss the code
that reads if from the device.  But they work, and the mib is
updated:

   tornado% snmpwalk -c public -v 2c -m +`pwd`/WR-SWITCH-MIB.txt wrs \
            .1.3.6.1.4.1.96.100.4

   WR-SWITCH-MIB::wrsVersionGw1.0 = STRING: fake-7cce708
   WR-SWITCH-MIB::wrsVersionGw2.0 = STRING: fake-5118070
   WR-SWITCH-MIB::wrsVersionGw3.0 = STRING: fake-7efeb16
   WR-SWITCH-MIB::wrsVersionHw1.0 = STRING: fake-3.30
