This change provides __restore/__restore_rt on x86 and __restore_rt on
x86_64 with unwinding information to be able to unwind through signal
frame via libgcc provided unwinding interface. See comments inlined for
more details.
Also remove the test that had a dependency on
__attribute__((cleanup(foo_cleanup))). It doesn't provide us with any
better test coverage than we have from the newer tests, and it doesn't
work well across a variety architectures (presumably because no one uses
this attribute in the real world).
Tested this on host via bionic-unit-tests-run-on-host on both x86 and
x86-64.

This change is to migrate the getaddrinfo tests defined in the old file
system/extras/tests/bionic/libc/common/test_getaddrinfo.c
to the new place bionic/tests/netdb_test.cpp.
The test here is more thorough, and catches a bug in getservbyname(3)
that was breaking getaddrinfo(3)'s ability to look up services by name
without a hint that would cause it to ask for a specific protocol.

When setting a repeat timer using the SIGEV_THREAD mechanism, it's possible
that the callback can be called after the timer is disarmed or deleted.
This happens because the kernel can generate signals that the timer thread
will continue to handle even after the timer is supposed to be off.
Add two new tests to verify that disarming/deleting doesn't continue to
call the callback.
Modify the repeat test to finish more quickly than before.
Refactor the Counter implementation a bit.

From the release notes:
Changes affecting future time stamps
Pacific/Fiji will observe DST from 2014-11-02 02:00 to
2015-01-18 03:00. (Thanks to Ken Rylander for the heads-up.)
Guess that future years will use a similar pattern.
A new Zone Pacific/Bougainville, for the part of Papua New
Guinea that plans to switch from UTC+10 to UTC+11 on
2014-12-28 at 02:00. (Thanks to Kiley Walbom for the
heads-up.)
Changes affecting time zone abbreviations
Since Belarus is not changing its clocks even though Moscow
is, the time zone abbreviation in Europe/Minsk is changing
from FET to its more-traditional value MSK on 2014-10-26 at
01:00. (Thanks to Alexander Bokovoy for the heads-up about
Belarus.)
The new abbreviation IDT stands for the pre-1976 use of UT+8
in Indochina, to distinguish it better from ICT (UT+7).
Changes affecting past time stamps
Many time stamps have been corrected for Asia/Ho_Chi_Minh
before 1976 (thanks to Trần Ngọc Quân for an indirect pointer
to Trần Tiến Bình's authoritative book). Asia/Ho_Chi_Minh has
been added to zone1970.tab, to give tzselect users in Vietnam
two choices, since north and south Vietnam disagreed after our
1970 cutoff.
Asia/Phnom_Penh and Asia/Vientiane have been turned into
links, as they differed from existing zones only for older
time stamps. As usual, these changes affect pre-1970 time
stamps only. Their old contents have been moved to the
'backzone' file.

Unless we completely redo how we build bionic (so that the object
files for libc.so get built separately from libc.a), we can't enable
ASAN here, as libc.a gets linked into static executables.

The mallinfo usmblks value returned by dlmalloc is a little misleading.
It's not the current max, it's the historical high water mark. This
leads to dumpsys meminfo producing native memory numbers that don't add up.
Change this to the real total footprint, not this high water mark.

valgrind seems to mess with the stack enough that the kernel will
report "[stack:pid]" rather than "[stack]" in /proc/self/maps, so
switch to the task-specific file instead to force "[stack]". (There
are two conditions in the kernel code that decides which form to
output.)

__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization
level, but does for -O0.
The rest of these didn't cause build failures, but they look suspect
and probably will, we just haven't caught them yet.

At -O0, the attribute warning on sprintf is actually triggered (why
doesn't this happen with -Os?!) and promoted to an error by -Werror.
asctime64_r() is a non-standard function, but the IBM docs state that
the buffer is assumed to be at least 26 characters wide, and the
format string does limit to that (assuming a 4 digit year, also
defined by the IBM docs).

For silvermont, the __popcountsi2 symbol does not get exported by libc.
But for atom, this symbol is exported. Since we already exported this symbol
for previous releases, it's better to just follow through and force
the export, but only for 32 bit. x86 64 bit will not export this symbol.

Unlike times(), clock_gettime() is implemented as a vDSO on many architectures.
So, using clock_gettime() will return a more accurate time and do so with less
overhead because it does have the overhead of calling into the kernel.
It is also significantly more accurate because it measures the actual time in
nanoseconds rather than the number of ticks (typically 1 millisecond or more).

Changes affecting past time stamps
America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.
Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
not 1920-01-06. The old entry was based on a misinterpretation of Shanks.
Some more zones have been turned into links, when they differed
from existing zones only for older time stamps. As usual,
these changes affect UTC offsets in pre-1970 time stamps only.
Their old contents have been moved to the 'backzone' file.
The affected zones are: Africa/Blantyre, Africa/Bujumbura,
Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.

This means all our stdio implementation is now the OpenBSD implementation.
The only thing we lose is the STDIO_THREAD_LOCK calls but they were no-ops
anyway.
We should probably talk to upstream about this. Either fix the locking or,
preferably, encourage them to move away from this pooling (especially since
there's no eviction policy).
