7dc2b7b30d Fix signal trampolines.
* LP32 should use sa_restorer too. gdb expects this, and future (>= 3.15) x86
  kernels will apparently stop supporting the case where SA_RESTORER isn't
  set.

* gdb and libunwind care about the exact instruction sequences, so we need to
  modify the code slightly in a few cases to match what they're looking for.

* gdb also cares about the exact function names (for some architectures),
  so we need to use __restore and __restore_rt rather than __sigreturn and
  __rt_sigreturn.

* It's possible that we don't have a VDSO; dl_iterate_phdr shouldn't assume
  that getauxval(AT_SYSINFO_EHDR) will return a non-null pointer.

This fixes unwinding through a signal handler in gdb for all architectures.
It doesn't fix libunwind for arm and arm64. I'll keep investigating that...

50321e2e66 [x86,x86_64] Fix libgcc unwinding through signal
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.

ba811120ae Migrate system/extra getaddrinfo test, and fix a bug in getservbyname(3).
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.

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.

62d84b1935 Fix race condition in timer disarm/delete.
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.
