Yanked out the cstring_alloc() and cstring_lineFromFile() functions from

utility.c and replaced them with get_line_from_file() from the new grep.c.
Also changed declaration in internal.h and replaced instances of
cstring_lineFromFile() in dc.c and sort.c with get_line_from_file(). Tested
them and they worked fine.
