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

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

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.

Combine leaks with same stacktrace
Combine similar leaks (those with identical stack traces) into a single
leak report, and sort the resulting leaks by total leak size across all
similar leaks and their references.

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.

imprecise mark and sweep native memory leak detector
libmemunreachable uses an imprecise mark and sweep pass over all memory
allocated by jemalloc in order to find unreachable allocations.
