In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Add struct_group() to mark the "info" region (containing struct DInfo and struct DXInfo structs) in struct hfsplus_cat_folder and struct hfsplus_cat_file that are written into directly, so the compiler can correctly reason about the expected size of the writes. "pahole" shows no size nor member offset changes to struct hfsplus_cat_folder nor struct hfsplus_cat_file. "objdump -d" shows no object code changes.
