Convert function fill_int32_saturate to take pointer to the data and asn.
The interpretation of pointer in struct snmp_oid is done in
fill_int32_saturate_pp.

From now, struct snmp_oid contais the pointer (p) which is up to the callback
function to know how to interpret the pointer.

It is easier to handle **data and *data in declaration of the oid_array.

From now function adding the data to snmp packet (fill_asn), just takes pointer
to the data and asn type. Interpretation of a pointer in struct snmp_oid is now
up to the callback function.

It makes easier to handle different data types.

snmp_get_next works only when requesting oid is valid. Otherwise it fails to
find next entry.

Due to the above the snmpwalk works only when the walk is started from
the existing oid. Since snmp walk scans only oids in the current branch,
there was a need to create a special oid .1.3.

$ snmpwalk -On -c public -v 1 192.168.1.20 1.3

The "community" string is public. We have tree items only: the host
name, the date and uptime.

The code is designed to make it simple any addition. But we only have
snmpget support, not snmpwak (i.e. "get next" query).

This is run on an host build (CONFIG_HOST_PROCESS) where the time and
date are not related to the real world:

   # snmpget -v 1 -c public 192.168.16.1 .1.3.6.1.2.1.1.5.0
   SNMPv2-MIB::sysName.0 = STRING: wrc

To update an entry when SFP database is in the eeprom, particular entry
is searched then simply updated.
On the other hand, when SFP database is in the flash simple update is
not possible. First old database is copied to the memory, then updated in
memory. After, the erase of the entire flash block is performed. At the end
updated information is written into the flash.

By making struct wr_minic non static it is possible for mini SNMP to get RX/TX
counters' values directly from the memory instead of writing a separate
function that will call minic_get_stats. Avoiding extra function saves about

EE_BASE_INIT did not include t24p and sfpcount. Due to that init script was overwriten
by adding the 4th SFP. Limit number of SFP in the database to 3. Keep init script's
starting address unchanged for backward compatibility.
SDB is not affected. Use maximum 4 SFPs in the database when SDB is used.

For other parties using the stats interface with the softpll we need
the minimal file that can be easily used in other projects (like SNMP on
the wr-switch).

Move to the softpll_export.h:
--struct spll_stats
--defines of seq_state from softpll_ng.c (SEQ_* and AUX_*)
--defines of align_state from spll_external.c (ALIGN_*)
--defines of mode from softpll_ng.h (SPLL_MODE_*)

"-I." is there, so instead of "../lib/ipv4.h" prefer <lib/ipv4.h>.

I thought moving ipv4.h to include, but then the name is possibly ambiguous
with other files in the -I search path. Thus I wanted to move
it from lib/ipv4.h to include/wrc-ipv4.h but that would require several
files to be changed.
