This commit implements a sequential extent allocator for the ZONED mode. This allocator just needs to check if there is enough space in the block group. Therefor the allocator never manages bitmaps or clusters. Also add ASSERTs to the corresponding functions. Actually, with zone append writing, it is unnecessary to track the allocation offset. It only needs to check space availability. But, by tracking the offset and returning the offset as an allocated region, we can skip modification of ordered extents and checksum information when there is no IO reordering.
