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.

Add unwind information for r7 in arm syscalls. It turns out that clang can emit code where the sp is saved in the r7 register on arm. Unfortunately, a lot of our syscalls overwrite that value while the syscall is executing, so unwinding through that syscall fails. Update the syscall generation code to add unwinding information for these uses. Bug: 28411713 Change-Id: Id51a5d43c058631bb50834527f93fa299bbcf759 2016-04-28 03:31:02 +02:00			`.cfi_register r7, ip`

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.
