9724ce3a09 Don't #define SYS_ constants unless they make sense for the current architecture.
Fixes the MIPS and x86 builds. strace tests whether syscalls
are supported using #ifdef of the appropriate SYS_ constant.

8ecf225827 Provide glibc-compatible SYS_* aliases for the __NR_* constants.
This helps us remove another external/strace bionic hack.

7582a9c119 Switch x86 syscall stubs over to the ENTER/END style of the ARM stubs.
Also update the x86 asm.h to support this; we need it for libm assembler
anyway.

Also clean up the _FBSDID hack in <sys/cdefs.h>.

c95eb57405 Clean up trailing whitespace in the kernel headers.
And fix the scripts so they stop letting trailing whitespace through.

faa0fdb119 arm syscall : for eabi call_default don't use stack
In the default case, we don't need to use the stack, we can save r7 with
ip register (that what does eglibc).

This allow to fix vfork data corruption
(see 3884bfe966), because vfork now don't
use the stack.

70b1668a76 remove obsolete SuperH support
We don't have a toolchain anymore, we don't have working original
kernel headers, and nobody is maintaining this so there is really
no point in keeping this here. Details of the patch:

- removed code paths from Android.mk files related to the SuperH
  architecture ("sh")

- removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh

- simplified libc/SYSCALLS.TXT

- simplified the scripts in libc/tools/ and libc/kernel/tools

fc2693110e libc: Update auto-gen scripts
Make the scripts use external/kernel-headers/original by default.

clean_header.py:  Document -k<path>, add -d<path>
find_headers.py:  Make kernel config files optional
update_all.py:    Allow setting the path to kernel headers on the command-line
update_all.py:    Better formatting of output on ttys
update_all.py:    Automatically perform "git add/rm" on affected files.
SYSCALLS.TXT:     Fix typo in __socketcall definition.
checksyscalls.py: Add support for superH architecture in the checks.
gensyscalls.py:   Automatically perform "git add/rm" on affected files.
cpp.py:           Fixed a bug that prevented certain type definitions to
                  be kept in the generated clean header (e.g.
                  struct ethtool_drvinfo in <linux/ethtool.h>)

All scripts will use the content of external/kernel-headers/original by default now.

The generated code removes all empty lines and trailing whitespace. This is useful
to ensure a unified output even if we change the parser again in the future.

The top-level disclaimer has been edited with update instructions to regenerate
the headers when needed.

Also, a warning is now inserted every 8th line in the final output:

/* WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS */

Changes under kernel/arch-arm and kernel/arch-x86 should correspond to whitespace
differences and additionnal struct definitions that were missed by the previous
parser implementation.

Change-Id: Icd1c056bacd766759f3e9b7bb5d63a246f3d656a

WARNING: If you run these script, do not submit the result to gerrit for now.
         It seems there are discrepancies between the content of original headers
         and those currently commited under bionic/libc/kernel/.

         (This problem is the main motivation to insert the warning repeatedly).

         Current list of issues:

           - Missing SuperH headers (i.e. external/kernel-headers/original/asm-sh)

95d751feac libc: Add ftruncate64 and improve 64-bit parameter syscall handling.
This patch improves the handling of 64-bit parameters in syscalls on ARM.
The ARM EABI mandates that 64-bit quantities be passed in even/odd register
pairs, which requires special treatment.

This allows us to simplify our implementations of pread() and pwrite()
and remove the C stubs for pread64() and pwrite64().

Also add ftruncate64() to <unistd.h>
