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.

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.

Replace unnecessary ARM uses of <sys/linux-syscalls.h> with <asm/unistd.h>.
For some reason, socketcalls.c was only being compiled for ARM, where
it makes no sense. For x86 we generate stubs for the socket functions
that use __NR_socketcall directly.

Use the kernel's MAX_ERRNO in the syscall stubs.

Clean up ARM assembler files to use ENTRY/END.
We also don't need legacy syscall support (non-"swi 0").
