hbitmap: assert that we don't create bitmap larger than INT64_MAX
We have APIs which returns signed int64_t, to be able to return error.
Therefore we can't handle bitmaps with absolute size larger than
(INT64_MAX+1). Still, keep maximum to be INT64_MAX which is a bit
safer.
Note, that bitmaps are used to represent disk images, which can't
exceed INT64_MAX anyway.
