[BZ #10918]
* sysdeps/unix/sysv/linux/bits/sched.h (__CPU_ISSET_S): Use __const
in cast to not throw away const-ness of parameters.
(__CPU_EQUAL_S): Likewise.
(__CPU_OP_S): Likewise.
* sysdeps/unix/sysv/linux/sh/bits/fcntl.h: Introduce new symbol
F_OWNER_PGRP and mark F_OWNER_GID obsolete. The kernel people made
this gratuitous change and we have to keep compatibility.
