Michael Bestas 07d61f1855 sm6150-common: Implement xtra-daemon control via property 
Default to false if the property is not set.
Device init scripts will need to be adapted to restart
loc_launcher service when property change is detected.

FUNCTION loc_read_conf_r_long (repetitive)
DESCRIPTION
Reads the specified configuration file and sets defined values based on
the passed in configuration table. This table maps strings to values to
set along with the type of each of these values.
The difference between this and loc_read_conf is that this function returns
the file pointer position at the end of filling a config table. Also, it
reads a fixed number of parameters at a time which is equal to the length
of the configuration table. This functionality enables the caller to
repeatedly call the function to read data from the same file.

config_table: table definition of strings to places to store information
table_length: length of the configuration table
