History
Joseph Myers 729f34028a Use single bits/shm.h for all architectures. 
After my patch to move SHMLBA to its own header, the bits/shm.h
headers for architectures using the Linux kernel still vary in a few
ways: the use of __syscall_ulong_t; whether padding for 32-bit systems
is present before or after time fields, or missing altogether (mips,
x32); whether shm_segsz is before or after the time fields; whether,
if after time fields, there is extra padding before shm_segsz.

This patch arranges for a single header to be used.  __syscall_ulong_t
is safe to use everywhere, while bits/shm-pad.h is added with new
macros __SHM_PAD_AFTER_TIME, __SHM_PAD_BEFORE_TIME,
__SHM_SEGSZ_AFTER_TIME and __SHM_PAD_BETWEEN_TIME_AND_SEGSZ to
describe the differences.

Tested for x86_64 and x86, and with build-many-glibcs.py.

	* sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add
	bits/shm-pad.h.
	* sysdeps/unix/sysv/linux/bits/shm.h: Include <bits/shm-pad.h>.
	(shmatt_t): Define as __syscall_ulong_t.
	(__SHM_PAD_TIME): New macro, depending on [__SHM_PAD_BEFORE_TIME]
	and [__SHM_PAD_AFTER_TIME].
	(struct shmid_ds): Define time fields using __SHM_PAD_TIME.
	Define shm_segsz and associated padding based on
	[__SHM_SEGSZ_AFTER_TIME] and [__SHM_PAD_BETWEEN_TIME_AND_SEGSZ].
	Use __syscall_ulong_t instead of unsigned long int.
	[__USE_MISC] (struct shminfo): Use __syscall_ulong_t instead of
	unsigned long int.
	[__USE_MISC] (struct shm_info): Likewise.
	* sysdeps/unix/sysv/linux/bits/shm-pad.h: New file.
	* sysdeps/unix/sysv/linux/hppa/bits/shm-pad.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/shm-pad.h: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/bits/shm-pad.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/shm-pad.h: Likewise.
	* sysdeps/unix/sysv/linux/x86/bits/shm-pad.h: Likewise.
	* sysdeps/unix/sysv/linux/hppa/bits/shm.h: Remove.
	* sysdeps/unix/sysv/linux/mips/bits/shm.h: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/bits/shm.h: Likewise.
	* sysdeps/unix/sysv/linux/sparc/bits/shm.h: Likewise.
	* sysdeps/unix/sysv/linux/x86/bits/shm.h: Likewise.
