Subject: [PATCH 0/2] lib: Fix bitmap_cut() for overlaps, add test

Patch 1/2 addresses the issue Yury reported with partially overlapping
src and dst in bitmap_cut(), and 2/2 adds a test that covers basic
functionality as well as this case.

v2: In 2/2, use macro to verify result, drop bogus Co-Authored-by:
    tag, both suggested by Andy Shevchenko, and avoid stack overflow
