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.

The local group is a sequence of libraries in default (breadth-first)
order. It allows RTLD_LOCALLY loaded library to correctly relocate
symbols within its group (see test-cases).
Local group lookup is performed after main executable and ld_preloads.

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.

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 trouble with cp is that if you're running a command directly (because
you're using gdb, say), you need to make sure you've copied the linker
and shell again if you've done a rebuild that caused a change there.

Otherwise the gcc compiler warning doesn't show up.
Add -Wno-error to fortify related tests. Fortify related tests
are expected to be examples of bad programs, and in many
cases shouldn't compile cleanly. Rewriting them to compile
cleanly isn't feasible nor desirable.

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).

The previous pthread_key_create_many test was really
pthread_key_create_all, which has proven very difficult to test
correctly (because it is affected by any other parts of the system using
pthread keys, and that can vary with test ordering). It also tested
expected values of PTHREAD_KEYS_MAX and the associated sysconf() value,
rather than those being in their own test.
Instead, split this test into a few distinct tests:
* pthread.pthread_keys_max
* pthread._SC_THREAD_KEYS_MAX_big_enough_for_POSIX
* pthread.pthread_key_many_distinct
* We actually didn't have a test to ensure that the keys we were
creating were distinct.
* pthread.pthread_key_EAGAIN
* Make sure pthread_key_create() will _eventually_ fail with
EAGAIN, not at a (sometimes incorrectly) predetermined maximum.

libc and libc++ both define std::nothrow. libc's is a private symbol,
but this still causes issues when linking libc.a and libc++.a, since
private isn't effective until it has been linked. To fix this, just
allow multiple symbol definitions for the static tests.
