Josh Gao c531ed6648 debuggerd_fallback: fix race. 
A race condition occurs when one thread takes more than a second to get
scheduled to handle the signal we send to ask it to dump its stack.
When this happens, the main thread will continue on, close the fd, and
then ask the next thread to dump, but the slow thread will then wake up
and try to write to the new thread's fd, or trigger an assertion in
__linker_enable_fallback_allocator.

Do a few things to make this less bad:
  - encode both target tid and fd in the shared atomic, so that we know
    who each fd is for
  - switch __linker_enable_fallback_allocator to return success instead
    of aborting, and bail out if it's already in use
  - write to the output fd right when we get to it, instead of doing it
    whenever the dumping code decides to, to reduce the likelihood that
    the timeout expires

Rajeev Kumar 7045003d0d Implement stats logging in LMKD. 
It implements logging of following atoms:
  -- LMK_STATE_CHANGED
  -- LMK_KILL_OCCURRED

We would like to gather memory metrics of the process killed by LMKD
because by gathering this info we would be able to analyze and improve
system health by potentially reducing memory footprint of the process.

This feature would be available on production builds.

To know more about this see: http://go/android-p-memory-metrics

Commit 3e235911 in bionic switched LP32's sigaction implementation over
to using the rt_sigaction syscall, matching LP64. Update our seccomp
policy to match.
