The kernel can hold references to binder objects that have no userspace
references. Allow libmemunreachable to call into libbinder and
libhwbinder to get lists of kernel references. Use undefined weak
symbols so that libmemunreachable will continue to work in processes
that do not have libbinder.

It depends on functionality in the bionic
allocator, which may get updated independently
of the vendor partition (as libc is in the LL-NDK).

Also, add a link to the .clang-format-2 for this directory and clang
format the files that changed.

Test: Boot bullhead.
Test: Run unit tests on bullhead. There are a few that fail, but they
Test: failed before and are not a result of this change.

Move the name of the "private/libc_logging.h" header to <async_safe/log.h>.
For use of libc_malloc_debug_backtrace, remove the libc_logging library.
The library now includes the async safe log functions.
Remove the references to libc_logging.cpp in liblog, it isn't needed because
the code is already protected by a check of the __ANDROID__ define.
Test: Compiled and boot bullhead device.
Test: Run debuggerd unit tests.
Test: Run liblog unit tests on target and host.
Test: Run libmemunreachable unit tests (these tests are flaky though).

I tested the following tests on a Nexus9 and linux host, and they
continued to pass:
/data/nativetest{,64}/bootstat_tests/bootstat_tests
out/host/linux-x86/bin/nativetest{,64}/bootstat_tests/bootstat_tests
/data/nativetest64/memunreachable_test/memunreachable_test
out/host/linux-x86/bin/nativetest{,64}/memunreachable_test/memunreachable_test
These continue to fail just like before this change:
/data/nativetest{,64}/sync_test/sync_test (was /system/bin/sync_test)
/data/nativetest{,64}/sync-unit-test/sync-unit-test
/data/nativetest/memunreachable_test/memunreachable_test
Test: See above
