Clean up <sched.h>. This patch switches to using the uapi constants. It also adds the missing setns system call, fixes sched_getcpu's error behavior, and fixes the gensyscalls script now ARM is uapi-only too. Change-Id: I8e16b1693d6d32cd9b8499e46b5d8b0a50bc4f1d

Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps.
