[PATCH v5 0/5] lib: rework bitmap_parselist and tests

[Yury Norov]

bitmap_parselist has been evolved from a pretty simple idea for long and
now lacks for refactoring. It is not structured, has nested loops and a
set of opaque-named variables.

Things are more complicated because bitmap_parselist() is a part of user
interface, and its behavior should not change.

In this patchset
 - bitmap_parselist_user() made a wrapper on bitmap_parselist();
 - bitmap_parselist() reworked (patch 2);
 - time measurement in test_bitmap_parselist switched to ktime_get
   (patch 3);
 - new tests introduced (patch 4), and
 - bitmap_parselist_user() testing enabled with the same testset as
   bitmap_parselist() (patch 5).

v3: https://lkml.org/lkml/2019/4/3/68
v4: https://lkml.org/lkml/2019/4/5/640
v5: - fix sadly missed '* step' in patch 4, as spotted by Guenter Roeck;
    - use _parse_integer() in bitmap_getnum() to avoid opencoding
      mentioned by Andy Shevchenko.
