-update snmp do use ppsi's shmem

It looks like ppsi's servo state provided in servo_state_name is not current
state but previous

Double values printed by ipc with shmem to verify readings. IPC to be removed
soon.
No need do update snmp's part of wr_mon since it will be removed (snmp will
use shmem directly).
Include implementation of shmem locks for read.

It was seen that phase setpoint read via shmem sometimes differs from value
read via ipc. However it shmem's value is more recent. Assignment of ipc's
cur_setpoint in ppsi's servo is done before setting to new value.

At the end of pstats and ppsi tables extra item was printed. 0 or null as an

no more elements instead of element 0 as it was so far.

Until now, ipc client was created in HAL to check if another HAL instance is

To prevent error from linker, order of linking libraries had to be changed.

Function hal_port_get_exported_state, fills structure hal_port_state with data
that are not available in SHM. It just assigns defines.
These defines are private to HAL, and assignment should be done in HAL.

Similar problem is for wrpc. There is a wrapper function that pretends to be
HAL. All HAL info should be filled in that function.

Fields added:
--uint32_t clock_period;
--uint32_t t2_phase_transition;
--uint32_t t4_phase_transition;

Additionally updated wrs_dump_shmem.c to dump new fields and the version number
of HAL SHM.
