This patch removes the files and replaces them with 'generic-y' statements, to avoid having to modify each copy when we extend sysvipc to deal with 64-bit time_t in 32-bit user space. Note that unlike alpha and ia64, the ipcbuf.h header file is slightly different here, so I'm leaving the private copy. To deal with 32-bit compat tasks, we also have to adapt the definitions of compat_{shm,sem,msg}id_ds to match the changes to the respective asm-generic files.
