Add a runtime feature (-R) flag for the free space tree. A filesystem that is mkfs'd with -R free-space-tree then mounted with no options has the same contents as one mkfs'd without the option, then mounted with '-o space_cache=v2'. The only tricky thing is in exactly how to call the tree creation code. Using btrfs_create_free_space_tree as is did not quite work, because an extra reference to the eb (root->commit_root) is leaked, which mkfs complains about with a warning. I opted to follow how the uuid tree is created by adding it to the dirty roots list for cleanup by commit_tree_roots in commit_transaction. As a result, btrfs_create_free_space_tree no longer exactly matches the version in the kernel sources.
