Support FiemapWriters that extend across multiple files. This introduces a new SplitFiemap class that will divide an allocation request across multiple FiemapWriters. This is primarily useful on filesystems that have onerous restrictions on maximum file sizes. Vfat, for example, supports a maximum of 4GiB, which is too small to satisfy larger userdata size requests.
