Several updates to Bionic crt*.o files to implement Linux/x86
stack unwind/exception handling.
Mark __dso_handle as hidden.
Note: Requires complete rebuild due to CRT changes. Google will
need to regenerate and check-in all the prebuilt x86 CRT object
files and libraries which link to them.

NOTE: This is a back-port from the internal HC branch.
This patch fixes a leak that occurs when creating a new
thread-specific DNS resolver state object.
Essentially, each thread that calls gethostbyname() or getaddrinfo()
at least once will leak a small memory block. Another leak happens
anytime these functions are called after a change of the network
settings.
The leak is insignificant and hard to notice on typical programs.
However, netd tends to create one new thread for each DNS request
it processes, and quickly grows in size after a > 20 hours.
The same problem is seen in other system processes that tend to
create one thread per request too.
The leak occured becasue res_ninit() was called twice when creating
a new thread-specific DNS resolver state in _res_get_thread().
This function could not properly reset an existing thread and was
leaking a memory block.
The patch does two things:
- First, it fixes res_ninit() to prevent any leakage when resetting
the state of a given res_state instance.
- Second, it modifies the _res_get_thread() implementation to
make it more explicit, and avoid calling res_ninit() twice
in a row on first-time creation.

This patch prevents the definition of various macros when <stdint.h> is
included from C++. The ISO C99 standard mentions that when this header
is included from a C++ source file, limit and constant related macros
should only be defined when asked explicitely by defining
__STDC_LIMIT_MACROS and __STD_CONSTANT_MACROS, respectively.
The <stdint.h> lacked the proper #ifdef .. #endif blocks for the
following macros:
INTPTR_MIN, INTPTR_MAX, UINTPTR_MAX, PTRDIFF_MIN, PTRDIFF_MAX
INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX,
INPTR_C, UINTPR_C, PTRDIFF_C, INTMAX_C, UINTMAX_C

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.

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)
On ARM there is currently no assembler optimized memmove in libc.
There is however a more optimized bcopy which copies long instead
of bytes where possible. This almost doubles the performance in
best case.

Add IN6ADDR_LOOPBACK_INIT macro to <netinet/in6.h>, as the kernel headers do not provide it anymore.
Update IPv6 kernel headers with new 2.6.37 headers, cleaned by update_all.py. (It wanted to do many other changes, most of them cosmetic, but I only included the IPv6 changes.)
