Zach Brown ff5a094833 scoutfs: store allocator regions in btree ...

Convert the segment allocator to store its free region bitmaps in the
btree.

This is a very straight forward mechanical transformation.  We split the
allocator region into a big-endian index key and the bitmap value
payload.  We're careful to operate on aligned copies of the bitmaps so
that they're long aligned.

We can remove all the funky functions that were needed when writing the
ring.  All we're left with is a call to apply the pending allocations to
dirty btree blocks before writing the btree.
