The ICU4J changes are not necessary for use on Android (since
we use the ICU4C .dat file), but updating them ensures that
the .jars in sync with everything else and the jars are currently
required for host tests.

Previous implementation of rwlock contains four atomic variables, which
is hard to maintain and change. So I make following changes in this CL:
1. Add pending flags in rwlock.state, so we don't need to synchronize
between different atomic variables. Using compare_and_swap operations
on rwlock.state is enough for all state change.
2. Add pending_lock to protect readers/writers waiting and wake up
operations. As waiting/wakeup is not performance critical, using a
lock is easier to maintain.
3. Add writer preference option.
4. Add unit tests for rwlock.

This makes unwind symbols 'protected',
which should prevent them from relocating
against libc++.so/libcutls.so.
This is temporary file and it is going
to be removed once libc.so stops exporting
them.

Apparently clang really doesn't want you to take the address of a builtin.
Since this is only a temporary hack, let's just shrug and accept that
clang-built volantis images won't work until we have new NVIDIA blobs.

NVIDIA binary blobs are assuming that __cache_clear, _Unwind_Backtrace,
and _Unwind_GetIP are all in some library that they link, but now we've
cleaned up this leakage, they're no longer getting it. Deliberately leak
the symbols from libc.so until we get new blobs.

This flag allows to force loading of the library
in the case when for some reason multiple ELF files
share the same filename (because the already-loaded
library has been removed and overwritten, for example).

This used to be handled by -fvisibility=hidden on libc_cxa, but that
was broken by the resolution of https://llvm.org/PR22419 (introduced
to Android in today's clang update).
Now we just use a version script that prevents these from being
re-exported from our shared libraries.

stubs.cpp gets string.h inherited from private/android_filesystem_config.h
it should not rely on this in the future. The intent is to move fs_config
function into libcutils and thus deprecate any need for string.h in this
include file.

These macros are also not used in glibc. And we should use
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP
and PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP instead.

This is initial implementations; does not yet handle
dlclose - undefined behavior, needs linker support to
handle it right.

It is due to a previous change "Let g_thread_list_lock only protect g_thread_list".
We need to add the newly created thread to thread_list even if
__init_thread fails, so the thread can exit successfully.

This is a patch testing whether we can use abort() instead of
returning ESRCH for invalid pthread ids. It is an intermediate
step to remove g_thread_list/g_thread_list_lock.

For DeathTests, we are testing the output of stderr to check if it is the
death we are expecting. To collect the output, Gtest redirects stderr to
a temporary file. But in __libc_write_stderr in libc_logging.cpp, we are
writing to stderr without a O_APPEND flag, so a new message will overwrite
a previous message.
The above situation makes almost all the DeathTests fail on host. Because
the expected message are always overwritten in host DeathTests. So I add
O_APPEND flag in __libc_write_stderr, which makes all host DeathTests pass.

As glibc/netbsd don't protect access to thread struct members by a global
lock, we don't want to do it either. This change reduces the
responsibility of g_thread_list_lock to only protect g_thread_list.

aligned attribute can only control compiler's behavior, but we
are manually allocating pthread_internal_t. So we need to make
sure of alignment manually.
