This CL adds utility functions to unwind the stack for a given thread on
Android ARM devices. This works on top of unwind.h and unwinds native
(C++) stack traces only. Unwinding a thread from another thread is done
by overriding the signal handler with a custom function and then
interrupting the specific thread.
