[BZ #19239] Don't include sys/sysmacros.h from sys/types.h.
This completes the deprecation and removal of this inclusion, which
was begun in the 2.25 release.

	* posix/sys/types.h: Don't include sys/sysmacros.h.
	* misc/sys/sysmacros.h: Remove the conditional deprecation
	warnings for the macros defined by this header.

+ * The macros 'major', 'minor', and 'makedev' are now only available from

+   further explanation.

+   <sys/sysmacros.h> is a GNU extension.  Portable programs that require
+   these macros should first include <sys/types.h>, and then include
+   <sys/sysmacros.h> if __GNU_LIBRARY__ is defined.
