Deprecate inclusion of <sys/sysmacros.h> by <sys/types.h>
The macros defined by <sys/sysmacros.h> are not part of POSIX nor XSI, and their names frequently collide with user code; see for instance glibc bug 19239 and Red Hat bug 130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the problem. * NEWS: Inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. * misc/sys/sysmacros.h: If __SYSMACROS_DEPRECATED_INCLUSION is defined, define major, minor, and makedev to issue deprecation warnings on use. If __SYSMACROS_DEPRECATED_INCLUSION is *not* defined, suppress previously-activated deprecation warnings for these macros and prevent subsequent inclusions of this header from having any effect. * posix/sys/types.h: Define __SYSMACROS_DEPRECATED_INCLUSION before including <sys/sysmacros.h>, and undefine it again afterward.
