Define struct rusage in sys/wait.h when required (bug 21575).
Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require sys/wait.h to include the definition of struct rusage. This is missing in glibc. This patch adds the required definition. struct rusage is moved to a new header bits/types/struct_rusage.h to avoid bringing in the whole of sys/resource.h (although the standards in question do allow the whole of sys/resource.h to be brought in). In the five bits/resource.h headers, the only variation between the definitions of struct rusage is that the sysdeps/unix/sysv/linux version is prepared for x32 (by having anonymous unions with __syscall_slong_t fields) and the others are not. Thus, this version is suitable for use generically (everything other than x32 simply has __syscall_slong_t the same as long int, so there are no API or ABI changes involved, and anonymous unions are already a required language feature for glibc headers elsewhere), and this patch uses it as a base for the single implementation of bits/types/struct_rusage.h. Tested for x86_64, and with build-many-glibcs.py. [BZ #21575] * resource/bits/types/struct_rusage.h: New file. * include/bits/types/struct_rusage.h: Likewise. * bits/resource.h (struct rusage): Include <bits/types/struct_rusage.h> instead of defining here. * sysdeps/unix/sysv/linux/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/alpha/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/mips/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/resource.h (struct rusage): Likewise. * resource/Makefile (headers): Add bits/types/struct_rusage.h. * posix/sys/wait.h [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8]: Include <bits/types/struct_rusage.h>
