Currently it has only test cases for SBThread.GetStopDescription() API.
Also modified lldb.swig to add typemap for (char *dst, size_t dst_len)
which occurs for SBThread::GetStopDescription() C++ API. For Python
scripting:
# Due to the typemap magic (see lldb.swig), we pass in an (int)length to GetStopDescription
# and expect to get a Python string as the result object!
# The 100 is just an arbitrary number specifying the buffer size.
stop_description = thread.GetStopDescription(100)
