Convert metadata block and file data extent allocations to use the radix allocator. Most of this is simple transitions between types and calls. The server no longer has to initialize blocks because mkfs can write a single radix parent block with fully set parent refs to initialize a full radix. We remove the code and fields that were responsible for adding uninitialized data and metadata. The rest of the unused block allocator code is only ifdefed out. It'll be removed in a separate patch to reduce noise here. Signed-off-by: Zach Brown <zab@versity.com>
