[PATCH v3 0/6] refine argparse library

[Chengwen Feng]

I found a couple of issues when I revisited the argparse_autotest
output, so got this patchset.

Chengwen Feng (6):
  argparse: refine error message
  argparse: remove dead code
  argparse: replace flag enum with marco
  argparse: fix argument flags operate as uint32 type
  test/argparse: refine testcases
  argparse: fix doc don't display two hyphens

v3:
- address Thomas's comment on 4/6 comit.
- add commit: fix doc don't display two hyphens.
v2: address David Marchand's comment:
- replace flag enum with marco.
- replace flag's hardcode with macro in test_argparse.c.
