crash_dump: fork a copy of the target's address space.
Reduce the amount of time that a process remains paused by pausing its
threads, fetching their registers, and then performing unwinding on a
copy of its address space. This also works around a kernel change
that's in 4.9 that prevents ptrace from reading memory of processes
that we don't have immediate permissions to ptrace (even if we
previously ptraced them).

Also, switch debuggerd_handler over to using android::base::unique_fd.

tombstoned: Add a shared library version of libtombstoned_client...
.. for ART and the frameworks to link against. In the new stack dumping
scheme (see related bug), the Java runtime will communicate with
tombstoned in order to obtain a FD to which it can write its traces.
Also move things around to separate headers that are private
implementation details from headers that constitute the public debuggerd
API. There are currently only three such headers :
- tombstoned/tombstoned.h
- debuggerd/client.h
- debuggerd/handler.h
