32-bit off_t is supported only for old 32-bit and compat ABIs. New ABIs are 64-bit length only. This patchset makes 64-bit length the default for off_t, and reverts it for old architectures where needed. It does not change the behaviour of existing code. First patch makes all compat users of generic unistd.h to use non-compat versions of openat and open_by_handle_at. Tile that requires old behaviour is turned around. Second patch introduces ARCH_32BIT_OFF_T config option, disabled by default, but enables it explicitly for existing 32-bit architectures.
