Hal creates shmem before waiting for SoftPLL to lock. By this other programs
waiting for HAL's shmem can start.
Please note that after this fix PPSi does not create shmem before lock.
It waits for HALs minipc server to be ready.

Before shmem is created, read hal mode first.

snmp_set_var_typed_value function does not epxect counter64 values as a
uint64_t, but as a struct counter64. Their binary representation differs by
order of 32bit words. By this it was wrongly seen as a endianess problem.
Since some status objects use 64bit values for calculations it is more
convenient to use uint64_t in our structures, then convert to struct counter64
just before passing data to the SNMP engine.

There was a special case when there was no update of pstats, but status was
recalculated. Since counters were not updated then deltas of counters were
within limits. It could happen that counters are growing, but statuses are
returning "ok".

For example problem was in the case, when object wrsPstatsHCRXDropRTUFull.1 was
increasing at every read:
$ snmpget WR-SWITCH-MIB::wrsPortStatusSfpError.1 # this triggers a read of
status ports
$ sleep 2
WR-SWITCH-MIB::wrsPortStatusSfpError.1 = INTEGER: sfpOk(1)
$ snmpget WR-SWITCH-MIB::wrsRTUStatus.0 # triggers only read of pstats, values
of status ports are cached (only 2 seconds elapsed)
WR-SWITCH-MIB::wrsRTUStatus.0 = INTEGER: error(2)
$ sleep 4
$ snmpget WR-SWITCH-MIB::wrsRTUStatus.0 # pstats value are cached, but deltas
are re-calculated and are equal to 0. This sould report error as well.
WR-SWITCH-MIB::wrsRTUStatus.0 = INTEGER: ok(1)
After the code is fixed the last one returns error(2)
