ac225780dd Move libc_logging to libasync_safe.
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).

cbe70cb0a8 debuggerd: advance our amazing bet.
Remove debuggerd in favor of a helper process that gets execed by
crashing processes.

9eb02c973f Define TARGET_IS_64_BIT when building libdebuggerd_client for android64.
This is needed to connect to the right debuggerd server for the crashing
process. Without this change, the following errors are observed, because a
32-bit process is trying to connect to the 64-bit debuggerd (as opposed to
debuggerd32):

  Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 14153 (static_crasher)
  debuggerd: handling request: pid=14153 uid=0 gid=0 tid=14153
  debuggerd: Not allowed to redirect action 0 to 32 bit debuggerd
