Remove SHOW_SNMP_GLOBALS, since SNMP doesn't use wr_mon for servo stats
anymore. It uses ppsi shmem.

 --SNMP_RW_COMMUNITY
-added threshold levels:
 --SNMP_TEMP_THOLD_FPGA

HAL at update of fan speed reads Switch's temperature sensors.
Sensors read:
-FPGA
-PLL (was read before to drive PWM for fan)
-Power supply left
-Power supply right

Additionally:
-add hal_temp_sensors structure to hal shmem, add current temperature and
 threshold values (to be implemented in later commits)
-increment HAL_SHMEM_VERSION
-update hal_shmem.h in ppsi
-update dump_shmem with new structure, add specific type for temperature
 sensors
-in hal_ports.c
 --rename struct wrs_shm_head *head to struct wrs_shm_head *hal_shmem_hdr
 --remove void *hal_port_shmem as not needed,
 --make struct hal_shmem_header *hal_shmem extern, defined in hal_main.c

-vendor name, part number

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.
