To avoid multiple copies of the same/simillar code template for scalar groups

Null is returned when there is unsuccessful read from dotconfig
(function libwr_cfg_get). Function atoi rely on valid string passed as
parameter. If dotconfig parameter does not exist, atoi will crash wrsw_hal.
Added checking whether valid string is returned from libwr_cfg_get.

Second test of $? value was not always result of command
"tftp $eth0.ipaddr/wrboot wrboot", but sometimes result of first if statement
(in case first tftp was successful).

In other words, when there was file wrboot-$eth0.ethaddr on tftp server, script
was still fetching and executing wrboot.

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

-vendor name, part number
