The new assume macro is used to setup the __IPC_64 value on ipc-priv.h. - Annexed the 'ipc: Refactor sysvipc compat type' to make it possible share the generic ipc_priv.h definions for all architectures. -- This patch refactor the internal sysvipc in two main points: 1. Add a new __ASSUME_SYSVIPC_DEFAULT_IPC_64 to infer the __IPC_64 value in wire-up or ipc syscall. The defaut value assumed for __IPC_64 is also changed from 0x100 to 0x0, aligning with Linux generic UAPI. The idea is to simplify the Linux 5.1 wire-up for sysvipc syscalls for some 32-bit ABIs (which expectes __IPC_64 being 0x0) and simplify new ports (which would not require add a ipc_priv.h to override the __IPC_64 value). 2. It removes some duplicated definition from sysvipc compat code at ipc_priv.h. The idea is also to make it simpler to enable the new wireup sysvipc on Linux v5.1. There is no semantic change expected on any port. Checked with a build against all affected ABIs. * sysdeps/unix/sysv/linux/ipc_priv.h (__OLD_IPC_ID_TYPE, __OLD_IPC_MODE_TYPE, __OLD_IPC_SEQ_TYPE): Define.
