libglusterfs: pass buffer size to gf_store_read_and_tokenize function
Previously if user set an option where length of key=value goes beyond
PATH_MAX (4096) character then tokenzing the option at the time of
reading configuration file will fail.
This is because of the we was having restraction in fgets to read maximum
of PATH_MAX (4096) length of character.
Consequence of this is when user try to restart glusterd, after setting
key=value length beyond PATH_MAX (4096) character, glusterd will not restart.
With this fix instead of PATH_MAX, consumer of gf_store_read_and_tokenize
function will decide the size of the buffer length.
