Have the server use the extent core to maintain free extent items in the allocation btree instead of the bitmap items. We add a client request to allocate an extent of a given length. The existing segment alloc and free now work with a segment's worth of blocks. The server maintains counters in the super block of free blocks instead of free segments. We maintain an allocation cursor so that allocation results tend to cycle through the device. It's stored in the super so that it is maintained across server instances. This doesn't remove unused dead code to keep the commit from getting too noisy. It'll be removed in a future commit. Signed-off-by: Zach Brown <zab@versity.com>
