From: Yury Norov <ynorov@xxxxxxxxxxx>
Subject: lib: new testcases for bitmap_parse{_user}

New version of bitmap_parse() is unified with bitmap_parse_list(), and
therefore:

- weakens rules on whitespaces and commas between hex chunks;

- in addition to

- allows passing UINT_MAX or any other big number as the length of input
  string instead of actual string length.

The patch covers the cases.
