Add/remove option to the option file section.
SYNOPSYS

file_location The location of configuration file to edit
option option to look for
option value The value of the option we would like to set
section_name the name of the section
remove_option This is true if we want to remove the option.
False otherwise.
IMPLEMENTATION
We open the option file first, then read the file line-by-line,
looking for the section we need. At the same time we put these lines
into a buffer. Then we look for the option within this section and
change/remove it. In the end we get a buffer with modified version of the
file. Then we write it to the file, truncate it if needed and close it.
RETURN
0 - ok
1 - some error has occured. Probably due to the lack of resourses
-1 - cannot open the file

DESCRIPTION
my_chsize() truncates file if shorter else fill with the filler character
my_chsize() truncates file if shorter else fill with the filler character.
The function also changes the file pointer. Usually it points to the end
