Instead of doing open-coded solution to generate JSON and prints, let's
reuse existing infrastructure and APIs to do the same as ip/*.
Before this change:
if (rd->json_output)
jsonw_uint_field(rd->jw, "sm_lid", sm_lid);
else
pr_out("sm_lid %u ", sm_lid);
After this change:
print_uint(PRINT_ANY, "sm_lid", "sm_lid %u ", sm_lid);
All the print functions are converted to support color but for now the
type of color is COLOR_NONE. This is done as a preparation to addition
of color enable option. Such change will require rewrite of command line
arguments parser which is out-of-scope for this patch.
