This was (sometimes) preventing FORTIFY_SOURCE related functions

If "n" is smaller than the size of "src", then we'll
never read off the end of src. It makes no sense to call
__strncpy_chk2 in those circumstances.
For example, consider the following code:
int main() {
char src[10];
char dst[5];
memcpy(src, "0123456789", sizeof(src));
strncpy(dst, src, sizeof(dst));
dst[4] = '\0';
printf("%s\n", dst);
return 0;
}
In this code, it's clear that the strncpy will never read off
the end of src.

From the tzcode2013e release notes:
Changes affecting Godthab time stamps after 2037 if version mismatch
Allow POSIX-like TZ strings where the transition time's hour can
range from -167 through 167, instead of the POSIX-required 0
through 24. E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the
new Fiji rules. This is a more-compact way to represent
far-future time stamps for America/Godthab, America/Santiago,
Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem,
Pacific/Easter, and Pacific/Fiji. Other zones are unaffected by
this change. (Derived from a suggestion by Arthur David Olson.)
Allow POSIX-like TZ strings where daylight saving time is in
effect all year. E.g., TZ='WART4WARST,J1/0,J365/25' for Western
Argentina Summer Time all year. This supports a more-compact way
to represent the 2013d data for America/Argentina/San_Luis.
Because of the change for San Luis noted above this change does not
affect the current data. (Thanks to Andrew Main (Zefram) for
suggestions that improved this change.)
Where these two TZ changes take effect, there is a minor extension
to the tz file format in that it allows new values for the
embedded TZ-format string, and the tz file format version number
has therefore been increased from 2 to 3 as a precaution.
Version-2-based client code should continue to work as before for
all time stamps before 2038. Existing version-2-based client code
(tzcode, GNU/Linux, Solaris) has been tested on version-3-format
files, and typically works in practice even for time stamps after
2037; the only known exception is America/Godthab.
Changes affecting API
Support for floating-point time_t has been removed.
It was always dicey, and POSIX no longer requires it.
(Thanks to Eric Blake for suggesting to the POSIX committee to
remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy
Heninger, Arthur David Olson, and Alois Treindl, for reporting
bugs and elucidating some of the corners of the old floating-point
implementation.)
The signatures of 'offtime', 'timeoff', and 'gtime' have been
changed back to the old practice of using 'long' to represent UT
offsets. This had been inadvertently and mistakenly changed to
'int_fast32_t'. (Thanks to Christos Zoulos.)
The code avoids undefined behavior on integer overflow in some
more places, including gmtime, localtime, mktime and zdump.
Changes affecting code internals
Minor changes pacify GCC 4.7.3 and GCC 4.8.1.
Changes affecting documentation and commentary
Documentation and commentary is more careful to distinguish UT in
general from UTC in particular. (Thanks to Steve Allen.)
From the tzcode2013f release notes:
Changes affecting API
The types of the global variables 'timezone' and 'altzone' (if present)
have been changed back to 'long'. This is required for 'timezone'
by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
These variables were originally 'long' in the tz code, but were
mistakenly changed to 'time_t' in 1987; nobody reported the
incompatibility until now. The difference matters on x32, where
'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.)

Monday in October.
Changes affecting time stamps before 1970
Pacific/Johnston is now a link to Pacific/Honolulu. This corrects
some errors before 1947.
Some zones have been turned into links, when they differ from
existing zones only in older data that was likely invented or that
differs only in LMT or transition from LMT. These changes affect
only time stamps before 1943. The affected zones are:
Africa/Juba, America/Anguilla, America/Aruba, America/Dominica,
America/Grenada, America/Guadeloupe, America/Marigot,
America/Montserrat, America/St_Barthelemy, America/St_Kitts,
America/St_Lucia, America/St_Thomas, America/St_Vincent,
America/Tortola, and Europe/Vaduz. (Thanks to Alois Treindl for
confirming that the old Europe/Vaduz zone was wrong and the new
link is better for WWII-era times.)
Change Kingston Mean Time from -5:07:12 to -5:07:11. This affects
America/Cayman, America/Jamaica and America/Grand_Turk time stamps
from 1890 to 1912.
Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46.
This affects Europe/Zurich time stamps from 1853 to 1894. (Thanks
to Alois Treindl).
Change the date of the circa-1850 Zurich transition from 1849-09-12
to 1853-07-16, overriding Shanks with data from Messerli about
postal and telegraph time in Switzerland.
Data changes affecting behavior of tzselect and similar programs
Country code BQ is now called the more-common name "Caribbean Netherlands"
rather than the more-official "Bonaire, St Eustatius & Saba".
Remove from zone.tab the names America/Montreal, America/Shiprock,
and Antarctica/South_Pole, as they are equivalent to existing
same-country-code zones for post-1970 time stamps. The data for
these names are unchanged, so the names continue to work as before.

This adds mmap64() to bionic so that it is possible to have
large offset passed to kernel. However, the syscall mechanism
only passes 32-bit number to kernel. So effectively, the
largest offset that can be passed is about 43 bits (since
offset is signed, and the number passed to kernel is number
of pages (page size == 4K => 12 bits)).

memcpy, memmove, and memset deliberately use __bos0. This is done
for two reasons:
1) I haven't yet tested to see if __bos is safe to use.
2) glibc uses __bos0 for these methods.

We used to just try any iface we'd been told about as a
fallback, but that will end up mistakenly using a secondary
network's dns when we really don't have a default connection.
It also messed up our detection of whether we were doing the
lookup on the default or not (we'd get back our secondary net
iface as the default, do the compare and think we were on default).
Remove the lies and let dns fail if we don't have an iface for it.

This change pulls the memcpy code out into a new file so that the
__strcpy_chk and __strcat_chk can use it with an include.
The new versions of the two chk functions uses assembly versions
of strlen and memcpy to implement this check. This allows near
parity with the assembly versions of strcpy/strcat. It also means that
as memcpy implementations get faster, so do the chk functions.
Other included changes:
- Change all of the assembly labels to local labels. The other labels
confuse gdb and mess up backtracing.
- Add .cfi_startproc and .cfi_endproc directives so that gdb is not
confused when falling through from one function to another.
- Change all functions to use cfi directives since they are more powerful.
- Move the memcpy_chk fail code outside of the memcpy function definition
so that backtraces work properly.
- Preserve lr before the calls to __fortify_chk_fail so that the backtrace
actually works.
Testing:
- Ran the bionic unit tests. Verified all error messages in logs are set
correctly.
- Ran libc_test, replacing strcpy with __strcpy_chk and replacing
strcat with __strcat_chk.
- Ran the debugger on nexus10, nexus4, and old nexus7. Verified that the
backtrace is correct for all fortify check failures. Also verify that
when falling through from __memcpy_chk to memcpy that the backtrace is
still correct. Also verified the same for __memset_chk and bzero.
Verified the two different paths in the cortex-a9 memset routine that
save variables to the stack still show the backtrace properly.

This change creates assembler versions of __memcpy_chk/__memset_chk
that is implemented in the memcpy/memset assembler code. This change
avoids an extra call to memcpy/memset, instead allowing a simple fall
through to occur from the chk code into the body of the real
implementation.
Testing:
- Ran the libc_test on __memcpy_chk/__memset_chk on all nexus devices.
- Wrote a small test executable that has three calls to __memcpy_chk and
three calls to __memset_chk. First call dest_len is length + 1. Second
call dest_len is length. Third call dest_len is length - 1.
Verified that the first two calls pass, and the third fails. Examined
the logcat output on all nexus devices to verify that the fortify
error message was sent properly.
- I benchmarked the new __memcpy_chk and __memset_chk on all systems. For
__memcpy_chk and large copies, the savings is relatively small (about 1%).
For small copies, the savings is large on cortex-a15/krait devices
(between 5% to 30%).
For cortex-a9 and small copies, the speed up is present, but relatively
small (about 3% to 5%).
For __memset_chk and large copies, the savings is also small (about 1%).
However, all processors show larger speed-ups on small copies (about 30% to
100%).

Create one version of strcat/strcpy/strlen for cortex-a15/krait and another
version for cortex-a9.
Tested with the libc_test strcat/strcpy/strlen tests.
Including new tests that verify that the src for strcat/strcpy do not
overread across page boundaries.
NOTE: The handling of unaligned strcpy (same code in strcat) could probably
be optimized further such that the src is read 64 bits at a time instead of
the partial reads occurring now.
strlen improves slightly since it was recently optimized.
Performance improvements for strcpy and strcat (using an empty dest string):
cortex-a9
- Small copies vary from about 5% to 20% as the size gets above 10 bytes.
- Copies >= 1024, about a 60% improvement.
- Unaligned copies, from about 40% improvement.
cortex-a15
- Most small copies exhibit a 100% improvement, a few copies only
improve by 20%.
- Copies >= 1024, about 150% improvement.
- Unaligned copies, about 100% improvement.
krait
- Most small copies vary widely, but on average 20% improvement, then
the performance gets better, hitting about a 100% improvement when
copies 64 bytes of data.
- Copies >= 1024, about 100% improvement.
- When coping MBs of data, about 50% improvement.
- Unaligned copies, about 90% improvement.
As strcat destination strings get larger in size:
cortex-a9
- about 40% improvement for small dst strings (>= 32).
- about 250% improvement for dst strings >= 1024.
cortex-a15
- about 200% improvement for small dst strings (>=32).
- about 250% improvement for dst strings >= 1024.
krait
- about 25% improvement for small dst strings (>=32).
- about 100% improvement for dst strings >=1024.

This optimized version is primarily targeted at cortex-a15.
Tested on all nexus devices using the system/extras/libc_test strlen test.
Tested alignments from 1 to 32 that are powers of 2.
Tested that strlen does not cross page boundaries at all alignments.
Speed improvements listed below:
cortex-a15
- Sizes >= 32 bytes, ~75% improvement.
- Sizes >= 1024 bytes, ~250% improvement.
cortex-a9
- Sizes >= 32 bytes, ~75% improvement.
- Sizes >= 1024 bytes, ~85% improvement.
krait
- Sizes >= 32 bytes, ~95% improvement.
- Sizes >= 1024 bytes, ~160% improvement.
Merge from internal master.

We notify debuggerd of problems by installing signal handlers. That's
fine except for when the signal is caused by us running off the end of
a thread's stack and into the guard page.

We cleaned up the auto-generated ones a while back to not touch
the stack unnecessarily if they have <= 4 arguments. This patch
cleans up some hand-crafted ones.
Also improve comments in clone.S.

pthread_getattr_np was reporting the values supplied to us, not the values we
actually used, which is kinda the whole point of pthread_getattr_np.
pthread_attr_setguardsize and pthread_attr_setstacksize were reporting EINVAL
for any size that wasn't a multiple of the system page size. This is
unnecessary. We can just round like POSIX suggests and glibc already does.
Also improve the error reporting for pthread_create failures.

Well, kinda... localtime.c still contains a bunch of Android-specific
hacks, as does strftime.c. But the other files are now exactly the same
as upstream.
This catches up with several years of bug fixes, and fixes most of the
compiler warnings that were in this code. (Just two remain.)

glibc doesn't have these, and they prevent ping from building out of
the box because it assumes it can define them.

From the release notes:
Changes affecting future time stamps:
Morocco's midsummer transitions this year are July 7 and August 10,
not July 9 and August 8. (Thanks to Andrew Paprocki.)
Israel now falls back on the last Sunday of October.
(Thanks to Ephraim Silverberg.)
Changes affecting past time stamps:
Specify Jerusalem's location more precisely; this changes the pre-1880
times by 2 s.
Changing affecting metadata only:
Fix typos in the entries for country codes BQ and SX.

Linux and *BSD kernels use opposite values to indicate pass/block
in ICMPv6 filters, and assign a different value to the
ICMP6_FILTER sockopt.
