Zach Brown 177af7f746 scoutfs: use larger metadata blocks ...

Introduce different constants for small and large metadata block
sizes.

The small 4KB size is used for the super block, quorum blocks, and as
the granularity of file data block allocation.  The larger 64KB size is
used for the radix, btree, and forest bloom metadata block structures.

The bulk of this are obvious transitions from the old single constant to
the appropriate new constant.  But there are a few more involved
changes, though just barely.

The block crc calculation now needs the caller to pass in the size of
the block.  The radix function to return free bytes instead returns free
blocks and the caller is responsible for knowing how big its managed
blocks are.
