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

The xattr system calls are required for the SE Android userspace in
order to get and set file security contexts. In particular, libselinux
requires these calls.

Add bionic libc to support readahead system call.
This is needed to enable sreadahead to work.

The kernel has supported this syscall for quite some time now,
but bionic did not. Now that there is a need for it, let's
add it to bionic.

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.

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)
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>

Bug 3107933
This adds the cpu_set_t type definition and related functions
and macros used to handle CPU thread affinity.
sched_getcpu()
sched_setaffinity()
sched_getaffinity()

Any of the setuid functions now updates /acct/uid/ with its own tid
before changing users. This is so we can properly account for cpu time
per uid.

Only provide an implementation for ARM at the moment, since
it requires specific assembly fragments (the standard syscall
stubs cannot be used because the child returns in a different
stack).
