And add '__restrict' where it appeared in the header prototypes.

Add support for fortify source level 2 to strncpy.
This will enable detection of more areas where strncpy
is used inappropriately. For example, this would have detected
bug 8727221.
Move the fortify_source tests out of string_test.cpp, and
put it into fortify1_test.cpp.
Create a new fortify2_test.cpp file, which copies all
the tests in fortify1_test.cpp, and adds fortify_source level
2 specific tests.

Pick up Linux kernel patch 2748e5dec7ca8a3804852c7c4171f9156384d15c
from 2007
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2748e5dec7ca8a3804852c7c4171f9156384d15c
[NETFILTER]: Fix iptables ABI breakage on (at least) CRIS
With the introduction of x_tables we accidentally broke compatibility
by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of
XT_TABLE_MAXNAMELEN, which is two bytes larger.
On most architectures it doesn't really matter since we don't have
any tables with names that long in the kernel and the structure
layout didn't change because of alignment requirements of following
members. On CRIS however (and other architectures that don't align
data) this changed the structure layout and thus broke compatibility
with old iptables binaries.
Changing it back will break compatibility with binaries compiled
against recent kernels again, but since the breakage has only been
there for three releases this seems like the better choice.

From the release notes:
Changes affecting current and future time stamps:
Palestine observed DST starting March 29, 2013. (Thanks to
Steffen Thorsen.) From 2013 on, Gaza and Hebron both observe DST,
with the predicted rules being the last Thursday in March at 24:00
to the first Friday on or after September 21 at 01:00.
Assume that the recent change to Paraguay's DST rules is permanent,
by moving the end of DST to the 4th Sunday in March every year.
(Thanks to Carlos Raúl Perasso.)
Changes affecting past time stamps:
Fix some historical data for Palestine to agree with that of
timeanddate.com, as follows:
The spring 2008 change in Gaza and Hebron was on 00:00 Mar 28, not
00:00 Apr 1.
The fall 2009 change in Gaza and Hebron on Sep 4 was at 01:00, not
02:00.
The spring 2010 change in Hebron was 00:00 Mar 26, not 00:01 Mar 27.
The spring 2011 change in Gaza was 00:01 Apr 1, not 12:01 Apr 2.
The spring 2011 change in Hebron on Apr 1 was at 00:01, not 12:01.
The fall 2011 change in Hebron on Sep 30 was at 00:00, not 03:00.
Fix times of habitation for Macquarie to agree with the Tasmania
Parks & Wildlife Service history, which indicates that permanent
habitation was 1899-1919 and 1948 on.
Changing affecting metadata only:
Macquarie Island is politically part of Australia, not Antarctica.
(Thanks to Tobias Conradi.)
Sort Macquarie more-consistently with other parts of Australia.
(Thanks to Tim Parenti.)

This uses the new code original submitted as memcpy.a15.S as
the base. However, the old code handled unaligned src/dst better
so that was spliced in. I optimized the original unaligned code by
removing a few unnecessary instructions. I optimized the a15 code by
rewriting the pre and post code. I also modified the main loop to add
a pld so that larger copies would not stall waiting for memory.
Test cases for the new memcpy:
- Copy all sized values from 0 to 1024 bytes, using whatever alignment
is returned by malloc.
For each alignment case described below, the test copied from 0 to 128
bytes.
- Src and dst pointers are both aligned to the same value, starting
at one going through every power of two up to and including 128.
- Src aligned to double word boundary, dst aligned to word boundary.
- Src aligned to word boundary, dst aligned to double word boundary.
- Src aligned to 16 bit boundary, dst aligned to word boundary.
- Src aligned to word boundary, dst aligned to 16 byte boundary.
- Src aligned to word boundary, dst aligned to 1 byte from a word
boundary.
- Src aligned to word boundary, dst aligned to 2 bytes from a word
boundary.
- Src aligned to word boundary, dst aligned to 3 bytes from a word
boundary.
- Src aligned to 1 byte from a word boundary, dst aligned to a word
boundary.
- Src aligned to 2 bytes from a word boundary, dst aligned to a word
boundary.
- Src aligned to 3 bytes from a word boundary, dst aligned to a word
boundary.
Cases to verify the unaligned source code properly aligns to a 16 bit
boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
4 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
8 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
12 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
16 + 128 bit boundary.
In all cases, a two byte fencepost was placed at the end of the
destination to verify that only the requested number of bytes were copied.

This adds __libc_fatal, cleans up the internal logging code a bit more,
and switches suitable callers over to __libc_fatal. In addition to logging,
__libc_fatal stashes the message somewhere that the debuggerd signal handler
can find it before calling abort.
In the debuggerd signal handler, we pass this address to debuggerd so that
it can come back with ptrace to read the message and present it to the user.

- eventfd.cpp and eventfd.s will output to the same file when building libc.a
out/target/product/*/obj/STATIC_LIBRARIES/libc_intermediates/WHOLE/libc_common_objs/eventfd.o
- And then `eventfd` will undefined when statically linked to libc.
Also add a unit test.

We use the system call constants from the kernel header files now,
so there's no need to check that they've been correctly transcribed
into SYSCALLS.TXT.
This is a work in progress. I've added TODOs to SYSCALLS.TXT explaining
what's left to do.

Currently, our getaddrinfo implementation does not conform to
any IETF standard. It follows draft-ietf-6man-rfc3484-revise-01,
but that draft has expired. Update the policy table to RFC6724.

pthread_create returns EAGAIN when it can't allocate a pthread_internal_t,
when it can't allocate a stack for the new thread, or when clone(2) fails
because there are too many threads. It's useful to be able to know why your
pthread_create just failed, so add some logging.

Need to get the defintion of the FITRIM ioctl(). Also need
to update the blk_types.h header file as fs.h includes it.

The <asm/unistd.h> files contain the canonical data, and
<sys/glibc-syscalls.h> contain new glibc-compatible names,
and if you #include the standard <sys/syscall.h> you get
both sets of names.

This lets us move all the ARM syscall stubs over to the kernel <asm/unistd.h>.
Our generated <sys/linux-syscalls.h> is now unused, but I'll remove that in a
later change.

Also add a more intention-revealing guard so we don't have loads of
places checking whether our inlining macro is defined.
