  [lldb-server] jThreadsInfo returns stack memory

This patch adds parts of the stack that should be useful for unwinding
to the jThreadsInfo reply from lldb-server. We return the top of the
stack (12 words), and we also try to walk the frame pointer linked list
and return the memory containing frame pointer and return address pairs.
The idea is to cover the cases with and without frame pointer omission.
