[PATCH v2 1/7] libsepol/tests: add ebitmap tests

["Christian Göttsche" <cgzones@googlemail.com>]

Preparation for several ebitmap related optimizations.

Signed-off-by: Christian Göttsche <cgzones@googlemail.com>
---
v2:
  - add more tests for multi node ebitmaps and for bits set at node
    bounds
  - test ebitmap_for_each_bit()
