Kyle J. McKay 68f4e1fc6a ewah_bitmap.c: do not assume size_t and eword_t are the same size ...

When buffer_grow changes the size of the buffer using realloc,
it first computes and saves the rlw pointer's offset into the
buffer using (uint8_t *) math before the realloc but then
restores it using (eword_t *) math.

In order to do this it's necessary to convert the (uint8_t *)
offset into an (eword_t *) offset.  It was doing this by
dividing by the sizeof(size_t).  Unfortunately sizeof(size_t)
is not same as sizeof(eword_t) on all platforms.

This causes illegal memory accesses and other bad things to
happen when attempting to use bitmaps on those platforms.

Fix this by dividing by the sizeof(eword_t) instead which
will always be correct for all platforms.
