[PATCH 2/4] Minimize sysdeps code involved in defining major/minor/makedev.


Presently sys/sysmacros.h is entirely defined in sysdeps.  This would
mean that the deprecation logic coming up in patch #4 would have to be
written twice (in generic/ and unix/sysv/linux/).  To avoid that, hoist
all but the unavoidably system-dependent logic to misc/, leaving a bits/
header behind.  This also promotes the Linux-specific encoding of dev_t,
which accommodated 32-bit major and minor numbers in a 64-bit dev_t,
to generic, as glibc's dev_t is always 64 bits wide.

The former Linux implementation used inline functions to avoid evaluating
arguments more than once.  After this change, all platforms use inline
functions, which means that three new symbols are added to the generic ABI.

New ports henceforth need only provide bits/sysmacros.h defining macros
__makedev_body, __major_body, and __minor_body.

While I was at it, I added a basic round-trip test for these functions.

ChangeLog:

	* misc/sys/sysmacros.h: New file with generic inline-function-based
	implementation of major, minor, makedev, derived from the old
	sysdeps/unix/sysv/linux/sys/sysmacros.h.
	* include/sys/sysmacros.h: New wrapper.

	* sysdeps/unix/sysv/linux/sys/sysmacros.h: Move ...
	* bits/sysmacros.h: ... here; only define __makedev_body,
	__major_body, __minor_body.
	* sysdeps/generic/sys/sysmacros.h: Deleted.

	* sysdeps/unix/sysv/linux/makedev.c: Move ...
	* misc/makedev.c: ... here; make generic.
	* misc/tst-makedev.c: New test.

	* misc/Makefile (headers): Add sys/sysmacros.h, bits/sysmacros.h.
	(routines): Add makedev.
	(tests): Add tst-makedev.
	* misc/Versions [GLIBC_2.24]: Add gnu_dev_major, gnu_dev_minor,
	gnu_dev_makedev.
	* posix/Makefile (headers): Remove sys/sysmacros.h.
	* sysdeps/unix/sysv/linux/Makefile (sysdep_routines): Remove makedev.

	* sysdeps/arm/nacl/libc.abilist: Add GLIBC_2.24,
	gnu_dev_major, gnu_dev_makedev, gnu_dev_minor.
