Christopher Ferris c463ba45c4 Add error reporting mechanism for failing Unwind.
Remove the logging of an error if a thread disappears before the unwind
can begin. This can happen, so allow the caller to determine if this
is really a problem worth logging.

Christopher Ferris 8540216028 Put BacktraceOffline code into a separate library.
BacktraceOffline is the only code that uses libLLVM. Create
a new shared library, backtrace_offline.so, that references this
so that including libbacktrace.so doesn't wind up pulling in libLLVM.
