Colin Cross f572b91c4f libmemunreachable: track kernel binder references
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.

Test: memunreachable_binder_test

Colin Cross a9939e9a23 Move libmemunreachable into namespace android
Putting libmemunreachable in the global C++ namespace was an oversight,
move it into namespace android.

Colin Cross 72d3881412 Add a helpful error message if GetUnreachableMemory fails
The primary reason for GetUnreachableMemory failing is selinux
blocking system apps from ptracing themselves.  Add a helpful
error message suggesting setenforce 0.

Colin Cross de42af013f libmemunreachable: fix long timeout on error
The collection thread should unblock the parent when it fails in order
to prevent a 100 second timeout delay.  Also reduce the timeout to 30
seconds, and fix a few log messages.
