Limit size of bitmap to 2million chunks.
...
When creating a file bitmap, choose a default size that
results in fewer than 2^21 chunks. Without this kmalloc
failure in the kernel becomes likely.

Use O_DIRECT to read bitmap files.
...
A pending patch to the kernel causes bitmap file updates
to not go through the page cache, so O_DIRECT is needed to
ensure that we read current data.

Create version-4 bitmaps if kernel supports it.
...
Version-3 bitmaps are host-endian. Version-4 are little-endian
and so more portable.
