'GPL-2.0-only' is used instead of 'GPL-2.0' because SPDX has
deprecated its use.

<title>dm space maps: improve performance with inc/dec on ranges of blocks</title>

When we break sharing on btree nodes we typically need to increment
the reference counts to every value held in the node.  This can
cause a lot of repeated calls to the space maps.  Fix this by changing
the interface to the space map inc/dec methods to take ranges of
adjacent blocks to be operated on.

For installations that are using a lot of snapshots this will reduce
cpu overhead of fundamental operations such as provisioning a new block,
or deleting a snapshot, by as much as 10 times.

More efficient way to iterate an array due to prefetching (makes use of
the new dm_btree_cursor_* api).
