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.
(cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.)

Make __set_errno hidden in asm.
This fixes the build after the -Bsymbolic change.

DO NOT MERGE Re-add .save directive for arm assembler code.
Restored the .save directives so that the libcorkscrew unwinder continues
to function.

Add cfi directives to all arm assembly.
Since the ENTRY/END macros now have .cfi_startproc/.cfi_endproc, most of the
custom arm assembly has no unwind information. Adding the proper cfi directives
for these and removing the arm directives.
Update the gensyscalls.py script to add these cfi directives for the generated
assembly. Also fix the references to non-uapi headers to the proper uapi
header.
In addition, remove the kill.S, tkill.S, tgkill.S for arm since they are not
needed at all. The unwinder (libunwind) is able to properly unwind using the
normal abort.
After this change, I can unwind through the system calls again.

Stop using the non-uapi <linux/err.h> header file.
We only need it for MAX_ERRNO, and it's time we had somewhere to put
the little assembler utility macros we've been putting off writing.

Remove dependencies on obsolete __ARCH_WANT_SYSCALL_DEPRECATED system calls.
(aarch64 kernels don't have these system calls.)
