Start a new out-of-tree repository, like linux-apfs-oot but with write support. To get the module to build independently, rewrite the Makefile and add a definition for the APFS_SUPER_MAGIC macro. Since the intention is to support a range of kernel versions, use preprocessor checks to handle kernels without statx, without iversion, and without SB_RDONLY. Provide a README file based on the original documentation, but with additional build and mount instructions. Add a LICENSE file as well. Signed-off-by: Ernesto A. Fernández <ernesto@corellium.com>
