Determining internal bitmap size is performed using two different
functions (bitmap_sectors() and calc_bitmap_size()) and in
getinfo_super1() it is calculated in yet another way. Each of these
methods give slightly different results. The most accurate is
calc_bitmap_size() but it also has a rounding issue. So:
- fix the rounding issue in calc_bitmap_size() using bitmap_bits()
- replace usages of bitmap_sectors() and open-coded calculations with
calc_bitmap_size()
- remove bitmap_sectors()
- move bitmap_bits() to mdadm.h as inline - otherwise mdassemble won't
compile (it does not use bitmap.c)

Commit f79bbf4f6904 ("super1: don't put the bblog at the end of the free
space.") changed the location of the bad block log to be after the
write-intent bitmap, but a fixed offset was used and it can make bbl
overlap with the bitmap, especially when using a small bitmap chunk.
This patch changes it to use the actual offset and size of the bitmap.
It also joins the cases for v1.1 and v1.2 superblock because the code
was very similar.

However, in the future please include a cover letter for multi-patch
sets.
